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?
It wouldn’t make much of a plot for the bad guy just to be after money. It doesn’t even work. If your goal was to make money, and didn’t have scruples, you wouldn’t spend who freaken knows how much effort learning martials arts, making rayguns, and you definitely wouldn’t go into a car throwing ramapage.
You would just get a job at Goldman Sachs or Wells Fargo. One thing I liked about Better Call Saul, he is in it for the money. A simple motivation that is not sympathetic.
