How is that any different from superman punching doomsday to death in death of superman storyline?superman didn't know doomsday was immortal. Superman punched doomsday to save himself and others. Luffy punched enel, crocodile and lucci to save alabasta, skypia, robin,everyone. Superman died punching doomsday . Luffy only fainted. Unlike, superman though luffy gives it his all. Why? Cause if he doesn't everyone connected to him would be killed. That's not the only body count goldenage superman has.
The only superman that doesn't kill is silverage and bronze age superman. The guy in my avatar. Every superman including postcrisis superman has killed. Don't forget how postcrisis superman killed zod.
