Having Aunt May die would completely alter Peter's lifestyle. That would mean that he'd have to fend for himself. He might get to keep the house, but he also might have to get a REAL job to pay bills and what-not.
Also, it would change the whole Spider-Man mythos. This is already proven to be a bad move, thus the whole deal with Mephisto.
It's a vicious circle, really.
