I guess that was a bad choice of words on my part. Not so much "tricked" as "corrupted". When you're tricked you're still one of the good guys, you just don't know what you're doing. When you're corrupted, you're fully aware of what's going on and some twisted sense of logic convinces you that it's okay anyway.
The people were the ones I meant as being tricked. Copy X doesn't mean to be evil (other than perhaps as in "a necessary evil"), and ultimately wants to preserve the human race, so no matter what the outcome should be better if you give Copy X free reign than ditto for Weil.
"Better" being relative, of course...
