Redeemed

Redeemed is the antagonist characters who are turned good.

Choosing their family over evil. Done with villains who have families and to care for them. They realize that their actions are actually hurting their spouses, children, siblings, or any other relatives in their family. Examples are Darth Vader Anti-Pops, Willaim Afton, and Older Brother.

Being memory-wiped or brainwashed into becoming a hero and deciding that they like their new personality and life better then their old one when they inevitably learn the truth. This is the rarest and most controversial form of a villain redeeming themselves since they did not turn good by their own free will and essentially had to be programmed into being good. The audience or reader meets them as a hero first, not knowing they are brainwashed or have fake memories. The "hero" does not know this either and is just as horrified as the viewer when they learn the truth about the horrible things they have done or regain their real memories, but they have spent so much time as a hero and living with an artificial good personality that they choose their new life over their former one and become true heroes.Examples are Freddy Fazbear and Bendy.

Betrayed by their fellow villainous allies/bosses, which made them choose to turn to the good side. After they antagonize the hero and their deed succeeds, their allies/bosses dump them or try to kill them straight away; either way, the said villain escapes. Having seen the error of their ways (and in the worst case, hunted down by the big bad or their former ally which left them no option but to join the heroes to survive), they choose to turn to the good side by joining forces with heroes. Examples are Darth Maul and Vegeta.
