ok, i still strongly believe he should be deleted for a few reasons, first of all, he was a normal guy who became a villain, not a fallen hero which a lot of people believe he is. secondly, an argument people use is that walter did horrible things for his family, which is a textbook definition of an anti-villain, not an anti-hero since none of the things he does are remotely heroic, and after season 2 he stops being an anti-villain and gets fully corrupted by greed. also, caring for your family isn't a heroic deed, vulture is a good dad and cares about his family, but could never be considered an anti-hero, also a lot of people bring up his redemption, but this is invalid since it's way too late and he only does like 3 heroic things, which is less than 5, so overall he wouldn't have enough heroic deeds.
he's sympathetic sure, but that doesn't make him a hero, it just makes him complex. however if you can counterargument all i said please explain why he should be on this wiki.
also i forgot to add that all his horrible actions make him one of the more heinous characters in the series so that should go into account, when reevaluating wether or not he is just a villainous protagonist or an actual hero
