Daredevil is my favorite Marvel superhero. Because he spares lives but is willing to kill people if he has to. In the Punisher he had Daredevil tied up and put a gun in his hand. He was about to snipe some mobsters but said the only way to save these people is to kill me. Daredevil was very sad and pulled the trigger and no bullets came out of course. And Punisher knocked him out to prove a point.
So in regards to someone who obliterates babies. Miracleman. I would bet my left nut he would kill him if it means he would escape from the phantom zone or whatever later.
