Superman must fly him to the air and punch him into space and let Wolverine lose his powers and let him die.
Technically Yes, but naturally he wasn't reallydead since everyone knew he was returning for future movies.
Assuming there's no kryptonite Batman, obviously

Superman and Doomsday were equally match if not more so Doomsday. But Superman had advantage of will power, as he always does. Superman used up all his (solar) energy with his final punch too take down Doomsday. Who also did a final punch to take down Superman, who had no energy left so "killed him" (As we know later it didn't) Not worth thinking into. The writers wanted Superman to die and they couldn't leave Doomsday undefeated by Superman, so it was only way to write it.
