Mother Teresa --- with an assault rifle
It is well known that all the superpower violence of the superheroes is designed only to save us from bad guys -- what could possibly be wrong with that moral stance ?
Saving an "us" who is not totally good but not really very bad either, from bad guys who are totally bad .
Well for starters, one might reply that in the real world the good and bad guys rarely morally divide up as neatly as all that , under all circumstances.
Again, we might ask how do the superheroes marvellously manage save us with all that superpower violence without that same violence being lethal to human lives ?
They do seem rather like a fairy tale version of the real world US Air Force.
