Well, that's to say that I believe in the devil, which I don't.
Can't believe in the Devil if you don't believe in some form of God.
Peter does believe in God, though, so really you're not putting yourself in his shoes at all.
Choosing between losing your beloved wife forever and losing your aged relative forever? Please. Even if you had an inkling of what you yourself would do in that kind of situation, you have no idea at all what anyone else would do in that kind of situation.
You know what, though? You're absolutely right: the Peter Parker that we've known for the last few years absolutely
would say yes to the devil. The Peter Parker that Quesada, JMS, and Bendis has been writing for recent memory, the one who's been the perpetual manchild, the emotionally-stunted timebomb, the inept amateur "hero" with no inspirational grounding in his character at all...yes, that guy definitely
would tell the devil to take away his wife, even if his
aunt's comatose spirit should appear to him and tell him to move the fck on. 'Cause, hey, that totally makes him more human or whatever.
See, all you guys just aren't seeing it. The Peter Parker that would treasure the time that he's had with the two women who loves him most in the world, the Peter Parker that would be the adult, seasoned champion that he's grown into, the Peter Parker who would truly prove himself worthy of being Marvel's flagship hero adored by millions in the world...
that guy hasn't been with us for a long, long time. The Peter Parker who we've seen since at
least the past two and a half years is the same exact person who we saw at the end of Amazing Spider-Man #545: an immature, incompetent excuse for a man who never learned to grow up. 'Cause that's what makes someone a relatable everyman, right?
So hey guys, why so serious?

In reality, we lost
nothing here.
