^Except it's still a deal with the devil, which is kind of anathema to the whole "hero" thing. And, again, it's completely illogical that the most brilliant minds, most powerful sorcerors, and most godlike cosmic entities in the Marvel universe couldn't fix a simple bullet wound even though they've been shown to be capable of far more miraculous feats in the past. And saying that it's just May's "time" doesn't cut it. It's a hollow excuse. If that were the case, then Mephisto shouldn't have been any more capable of changing May's fate than anyone else. It's grossly inconsistent, arbitrary storytelling. There's no legitimate reason why a deal with the devil would've been Peter's only possible recourse.
