i wonder who the true ml is for this...

What will happen to her ex? Spoilers?

"Nudolf, da ned-nosed naindeer!"

I'm gonna be honest, I'm tired of this trope of heroes magically reedeming villains that have killed thousands of people.
Nana was onto something saying that some people can't be forgiven or redeemed, they can't with just a lame i'm sorry for killing and hurting you all.
Most villains just don't need to have a sad backstory, some are just plain evil and that's it but for some reason shounen mangakas think it's necessary to do a depressing backstory for them because if not, how will the villain be redeemed by the public or hero??
This reminds me of Aang being unable of killing fire lord Ozai because he might be forgiven""" I understood where Aang came from and Deku too but we go back to the point Nana made.
If you disagree then it's okay, i'm just giving my opinion about a trope that just fucks me up
