also for non-kiiller examples of controversy you have Plastic Man from DC comics who is known for such acts as turning himself into a living toilet, spying on women in showers and other perverted behavior that makes him one of DC's most "wtf" heroes outside of Vertigo titles (as in Plastic Man is NOT considered a Mature title, despite all the above being in it).

on Marvel's side there's the infamous Hank Pyme wife-beater moment that was originally the result of bad comic editting but became a real thing in the Ultimates universe - in fact the entire Ultimates universe had very disturbing heroes who were basically sociopaths.
