Well I wanna discuss it NOW!
"Word of God" disagrees with you.
From X-compendium:
CONNECTION TO OTHER WORKS
The setting of Rockman X is established about 100 years after the world of Rockman. It seems that after Dr. Light built Rockman, he developed X as a still more advanced version. Also, someone resembling Wily can be glimpsed in Zero’s vicinity.
I mean, it seems to me that if Wily can make the MM9 robots up and say "geez, the humans are wrong ... we CAN still be usefull" and MM to say "geez, I guess I don't really reason with robots, I am no better than Wily's being" then, even though Capcom says X thinks on a deeper level, I don't think that nessasarily holds up. I can't talk too much of the X series, my intrest / knowledge is spotty, but I do recall Alia having some mixed feelings about Gate. Not that she turned rogue, but she had mixed feelings.
I'd say a good place to start would be IHX, that alone is a grand example of the entire concept of X's worrying. All the other games simply put focus on it by talking about how X's compassion is over the top and how he might be fit to one day guide the world to unite humans and Repliroids. Then there's the manga, which also hits you over the head with the concept. Whilst X worries much deeper than others, it doesn't stop others from worrying alltogether. All Repliroids are after all based on X.
There are however also Repliroids that barely worry at all, but they have the ability to determine right and wrong for oneself, even if highly biased thoughts come from them. Sigma himself barely worries, barely hesitates, barely has any compassion to speak of. The same counts for VAVA and Sigma's new generation.
When you consider it this way, X's heightened worrying leads to over the top compassion for all living beings, Sigma's lack of worrying makes him a psychopath. Regular Repliroids are in the middle, just normal people, neither saints nor demons.
All of the above are capable of determining right and wrong because they have "Kunou Kairo" (suffering, distress, affliction, anguish, agony circuit) installed. That circuit is one target for the Sigma Virus to control the "heart", by changing their views of right and wrong, their allegiance changes. It's just that the how well it functions changes the effects visible on the outside. Ranging from Sigma to X.
When compared to the older robots, who never had X's circuit, it's obvious that these robots are not psychopaths like Sigma, they have something else installed to avoid that. Between those robots and Repliroids, all have "Shikou Kairo" -thought- circuits, which allow for independent thought and reasoning.
The key difference between those robots and Repliroids is "Ryoushin Kairo" versus "Kunou Kairo", the conscience circuit verses mental suffering circuit. Because Rock has a strong sense of justice, his Conscience yields similar results to X's worrying. Both are circuits with the explicit function of creating a conscience. Between regular robots, who have less of a sense of justice, and regular Repliroids, who worry much less than X, the results are also comparable.
Looking at the definition for both circuits, the only thing that pops out is the inability of the conscience circuit to invoke growth of the conscience, growth of their views of right and wrong. That's where X's circuit is the huge improvement. It sheds away the final limitation in the ability to truly be free by allowing variability in the conscience.
Rock thinks within the confines of the conscience Dr. Right programmed him to have. X's conscience can evolve away from the conscience that Dr. Right programmed him to have. This growth is subtle, but to Dr. Right, it marks a new epoch in robotics where robots can truly be equel to 'people'. Giving robots that ability is what stops the humans from considering robots as just tools and much more as equals. Rock might act just as much as a person as X, but to the humans that created him that are aware of his limitations as a robot, that alone is justification to consider him just a tool to be used and thrown away. When they become aware that these robots will adjust their views of right and wrong, humanity will be far more cautious to simply deem them as tools, even though unavoidable, some still will.
If someone programmed a robot to know absolutely in its conscience that "killing is wrong" then a robot with a Kunou Kairo installed can come to the conclusion of its own accord, given time, that "killing is right." The keyword in Repliroids is "evolution", their conscience can evolve, their body can evolve. Previous robots were able to evolve their thought patterns and personality, but not their "conscience" and "bodies." That's where X and the Repliroids are different.
The effects might not be as profound as you want it to be, but still it is there. That this effect isn't as pronounced as it can be shows without a doubt how close to the holy grail of free willed robots the robots Right made were from the very beginning. Those robots were 99% of the way there, X and all Repliroids just fill in the final 1% of the equation.
Emphasizing once more: thought and reasoning is the same, the key difference lies with the conscience.
"X" IS THE FIRST OF A NEW GENERATION OF ROBOTS WHICH CONTAIN AN INNOVATIVE NEW FEATURE - THE ABILITY TO THINK, FEEL AND MAKE THEIR OWN DECISIONS." This statement is total BS. Now X's ability to worry without thinking humans or robots are superior is considered to be what is different, but this is a retcon. The first reason they gave us it definately BS.
DR. LIGHT: I granted X special powers that no other robot possesses. Utilizing his conscience, he is able to think, worry and act entirely of his own accord. Dr. Right says something similar in IHX, so as you can see, it isn't bullshit, it's simply an oversimplification and if you actually look at the japanese subtitled X1 warning, it's partially a mistranslation on Japan's part.
Furthermore, I can not stress enough that X's ability to worry is NOT a retcon! It's included in the very first game's manual! THREE versions of the same text are included within the very same package you would have bought 15 years ago!

Version1, English RockmanX game warning:
"X" IS THE FIRST OF A NEW
GENERATION OF ROBOTS WHICH
CONTAIN AN INNOVATIVE NEW
FEATURE - THE ABILITY TO
THINK, FEEL AND MAKE THEIR
OWN DECISIONS. HOWEVER THIS
ABILITY COULD BE VERY DAN-
GEROUS. IF "X" WERE TO BREAK
THE FIRST RULE OF ROBOTICS,
"A ROBOT MUST NEVER HARM
A HUMAN BEING", THE RESULTS
WOULD BE DISASTROUS AND I
FEAR THAT NO FORCE ON EARTH
COULD STOP HIM.
APPROXIMATELY 30 YEARS WILL
BE REQUIRED BEFORE WE CAN
SAFELY CONFIRM HIS RELI-
ABILITY. UNFORTUNATELY I WILL
NOT LIVE TO SEE THAT DAY,
NOR DO I HAVE ANYONE TO
CARRY ON MY WORK. THEREFORE,
I HAVE DECIDED TO SEAL HIM
IN THIS CAPSULE, WHICH WILL
TEST HIS INTERNAL SYSTEMS
UNTIL HIS RELIABILITY HAS
BEEN CONFIRMED. PLEASE DO
NOT DISTURB THE CAPSULE
UNTIL THAT TIME.
"X" POSSESSES GREAT RISKS
AS WELL AS GREAT POSSIBILI-
TIES. I CAN ONLY HOPE FOR
THE BEST.

Version2, Japanese RockmanX game Warning:
“X” is a new type of robot with more complex, human-like mental capabilities. However, these capabilities are also extremely dangerous. If “X,” of his own volition, ever broke the basic law of robotics, “A robot must not injure a human,” likely nothing could stop him, and the results would be fearsome.
If I had 30 years, it would be possible to confirm his safety. However, my life will not last that long, and there is no one to whom I can entrust my research. Therefore I will seal him in this capsule. This capsule will test his internal structure for me until his safety is confirmed. Until then, please do not open the capsule.
“X” is laden with both unlimited possibility and unlimited danger. I just hope it turns out for the best.

Version3, Japanese RockmanX manual warning:
“X” presents many problems inconceivable in existing robots. There is a danger he may worry over or question even the absolute requirement for robots, “Do not harm a human.”
The act of worrying in “X” marks a new epoch in robotics and is the first time this experiment has succeeded, but if it extends to matters that by their nature must not be questioned, it would be disastrous. In the worst case, if a robot were to harm humans deliberately, humankind would tremble with fear the like of which was unknown even in the days of the “Dr. Wily” incidents…
I conclude that “X” is an extremely dangerous being. If I am to send “X” out into the world, he must have a verification period of 30 years at the least. However, I do not have that long to live, and regrettably there is no one who understands all my research to carry it on for me.
Therefore I seal “X” here. If by some chance there is someone who discovers this capsule, as long as “X’s” thinking has not been fully analyzed, please leave him untouched. “X” is a robot laden with both unlimited possibility and unlimited danger…

Because these are games meant for ACTION, the plot presentation of the game's was minimized, good portions of the story come from the game manuals and the subsequence guidebooks. The much more in depth warning in the manual is meant to be the version that's the most accurate and deep, and was thus even included in X-compendium more than a decade later. That extended warning was even written BEFORE the journal of Dr. Cain ever made it in any of the manuals. That journal was initially written for MEGAmanX and then adapted for the ROCKmanX pc port to be included in the X-compendium a decade later.
So, why do we, who often cite things like Cain's journal from the manual as being part of how the series from the day 1, go around claiming the concept of "worrying" is a retcon when it even precedes that infamous journal? If there's anything, it's our lack of info as people that can only speak English and are reliant on Capcom of America's localizations, that's at fault.
See, Bass just feeling an obligation to Wily isn't quite enough for me to accept that he sees humanity as a whole as superior. Even his line of "but humans made us" doesn't really say superior. It could say "superior", but it could also say "eaqual". He never treats Wily as his superior. And doesn't try to be useful to mankind. Okay, he displays obligation to Wily. But obligation and superiority are two different things.
You're taking "bias" to be absolutely one extremely over the other, it's not so extreme, it's all about subtlety again. X's circuits are meant to provoke complete non bias by constantly forcing growth of his conscience to acquire that exact 50-50 equality for all races and individuals to judge solely on actions. For previous robots there's no growth, so their bias, which can never be exact equality, is always the same. In certain situations they will favor a human over a robot, one individual over another, or vice versa. They're simply stuck with whatever conscience they have been given by their creator, no matter what the contents of these consciences actually contain. To establish true equality of judgment in such a static system, is akin to an impossibility.
