Would a character based around brainwashing villains into doing good things, be good?

Would a character based around brainwashing villains into doing good things, be good?

Would this be a cool idea for a superhero?

Its fairly lame and one-note.

He'd be the anti-hero the other heroes and the villains would work against.

If he is really trying to be good, would they?

I could see the villains attacking him. But even the most goody-two shoes hero would have a hard time fighting a dude who is genuinely trying to help people.

He would need to be sneaky. First, to avoid getting murdered by sneaking into a super-villain lair and hypnotizing them. And then to avoid being found out by those who want to know why Lord Spinefucker is suddenly using his skullripping strength for good.

Lord skullbreaker might be a little out of his league.

Right now he pays mercenary villains to do good things, anonymously.

Then he brainwashes catburglers serial killiers, people who live for crime.

He kills people who are too far gone for brainwashing, like the joker.

Or he will

Somewhere in Neutral Good territory maybe.

Oh the fun stories that come from a righteous tyrant
>BBEG is former good guy
>not fallen but successful

everyone loves that shit

Identity Crisis was dumb and bad

What is evil, anyway? Is there reason to the rhyme? Without evil there can be no good so it must be good to be evil sometimes!

Depends on how you define "brainwashing".
If a hero sets up a rehabilitation facility for super villains that encourages reflection on their prior habits, provides therapy for any destructive traumas they may have suffered, and teaches empathy then really you're just a very specialized prison warden/rehab clinic. The villains can always reject the teachings, and keep being shitheads (who are safely locked up).
If you're straight up altering their personality and removing their ability to make choices of their own free will, you're getting into villain territory. It's basically "A Clockwork Orange": stripping someone of their right to choose between good and evil is inhumane, even if it's done with the best intentions. It also gets into some fun slippery slope territory. After all, if you start out just removing a villain's negative impulses to make them more perfect, why not expand that to the civilian populace? You could have the brainwasher's ultimate goal to create a placid utopia full of kind-hearted ubermensch who are utterly incapable of moral choice that he doesn't approve of.
Could be a fun anti-villain actually.
