I was watching One Hour Photo, and was wondering what was the first movie or TV show that featured a character that was a villain that happened to be a normal person.
By 'normal', I mean normal in the sense that they could be like any average person (not crazy or a lunatic in their ideals), someone who may have just gotten the wrong facts about something to make them do the wrong thing, even though they may think from their point of view they are doing the right thing.
This can include characters that are situationally bad while still inherently good (they don't need to be fully bad).
Note: I hope this question isn't too open to interpretation because of what is considered good or bad, though this is confined to the movie or TV show that they appear in and not general modern ethics. If it is indeed the case please let me know so that I can delete it (if not closed earlier).
