There are many delusional PE villains who do have a good point somewhere in ideology and could easily be an extremist if they didn't do a certain thing pertaining to it. I'm curious, what are some good examples you guys have of that?
For me, I think that applies to Proximus Caesar and Syndrome very well. Proximus Caesar was partially right about his distrust in humans and his goals seem understandable from a surface-level view, but he proves himself to be a hypocrite with his atrocities committed against his own kind and his lust for personal power. Syndrome's "when everyone's super, nobody is" quote is actually true in many ways and I think he could've passed off as an extremist if it wasn't for the fact that he monitized his gadgets rather than just giving them away to people without powers.
