Spoiler speak after the jump.
I was reading this story over at iO9 and a thought popped in my head.
At the end of Infinity War Steve Rogers mutters “Oh, God”. What if in that moment he realizes what happened, half the universe died, and he was still alive. What if he had hoped if it happened that he would have died as well? He has exisited for a long time. Fought many fights. What if he is tired and would like to pass on like those he was born with. What if he had secretly hoped that he would be in the half that died?
