Its good they are only brutalities, it is against the very fabric of DCU for their characters to kill. Batman is the only one I am aware of that ever did and he had no other choice in the circumstance.
Balderdash! One of the most disturbing things about modern comics is how they combine the murderous, grim-and-gritty villains with the naive notions that heroes can never kill and villains can escape custody with minimal explaination. If villains can’t be killed or held, they can never be punished. I don’t think heros should go around killing villains willy-nilly, but it is appropriate in certain situations. If Batman had killed the Joker after it became obvious he could never be held in a prison or asylum, countless innocents would have been spared.
In short, it would be fun to see Superman crush Sub-Zero’s head.
