With flying humans, magicians, and talking trees being just some of the things that people accept as perfectly normal in comics, it's fair to say that the medium more or less exists to make you ask yourself impossible questions.
Often, this revolves around what you would sacrifice to save either the world or your loved ones, as even characters with insane powers still have to make difficult decisions to which there really isn't a right answer.
But seeing the likes of Batman and Iron Man struggle to deal with these impossible issues can make trying to work out what you'd personally do even more confusing, as if a bunch of fictional geniuses can't figure out what to do, your chances seem even more limited.
This isn't a sad thing though, because it does work to massively humanise figures who can appear to have all the answers by giving them a scenario where it's to some degree a lose/lose situation.
Because, no matter how worked out you've got your life, you're still gonna struggle when you're presented with the choice of either eating your twin or dooming the world.
