Superior Iron Man was actually pretty solid for a villain.

Based on those observations, yeah, Iron Man could be considered an anti/hero. Albeit that it was mostly concerning business affairs or tyrannical decisions.

Wait, wait, what about redemption, can't some characters who started off as villains become heroes, like hawkeye and black widow, weren't they iron man villains who become avengers members? and what about Venom, Doc Ock, Norman Osborn (aka the Gold Goblin), Quicksilver, and Scarlet Witch, well not so much her after M-Day, but still, there are some who started off as evil, but slowly gained character development and turned into the adorable heroes we loved today?

Yeah, probably, but really only depends if they did crimes back in the day, but are now reforming and finally became a hero.

Naw i think you definitely can be redeemed. Former villains can be heroes if they work to it. Its been 50 years or so since Quicksilvers been a villain

Yup.

But then there/s characters who tetter totter, like Magneto.

Yeah, and that would mean that he’s worked with heroes on certain occasions whenever there’s a bigger, badder threat, right?

Well not quite. Magneto is very unsable mentally. But he's been a full flegged hero. For times he's fully aligned with the xmen. He's had his own xmen teams.

Since the 90s to current day he's actually been a hero more often than villain. He's spent most of it on the same side as the xmen usually.
