For hypothetical example; Father/son duo are criminals, harming, killing, and stealing innocent civilians. Superhero fights them, resulting in the father dying. Son is now portrayed as a sympathetic villain because all he wants is to avenge his father… despite all the fathers of children they murdered whilst comitting crimes.
Side question; do you feel sympathy for the villains portrayed like this?
Doesnt real life work that way? All the ways of doing crimes were pretty much figured out before any of us were born.
