Well, when you put it like that... but fate keeps tripping him up.
Heck, maybe fate IS trying to balance the scales for him cheating it with his Spider Sense..LOL! (That would be one way to really pile on the Parker guilt complex, if all his, and his family and friends troubles, really were his fault. That certinly would be a sure fire way to creat an alternate 'Spiderman No More' tale..)
