Peter routinely becomes Spider-man over going on dates with his girlfriends, being unavailable to them because he's too caught up trying to stop villains when in social situations and vice versa, has problems getting things to May when she needs them like groceries and generally being a flake and he knows this screws up his life but does it anyway.
He's not Wolverine, there's a reason why his first reaction is to dodge bullets than tank them. He has a higher healing factor, he's not bullet proof like Thor is. The more wounded he becomes, the easier a target he becomes when fighting people.Peter's been shot numerous times, but he recovers because he has an advanced healing factor. Not Wolverine levels but more than any ordinary human. It's also very hard to shoot Spider-Man because of how fast he moves and his Spider-Sense.
As much as the writers want them to. Spider-man himself is not a factor, it's the writers, and it's not like villains don't rotate to other heroes. Trapster fights both the FF and Spider-man, for instance. Bullseye's even taken a shot at him.And how much time do you think the Fantastic Four and the Avengers will be wasting tackling with Spider-Man villains when they could devote all their time to cosmic and mystical threats as well as the Masters of Evil. It's because Spider-Man holds down so much by himself that other teams of heroes can do what they can do.
Haven't read AF #15 but I'm an avid readers of Spider-man comics. I was mistaken.Have you read Spider-man comics? Or for that matter just Amazing Fantasy #15? Where was this ever stated in the comics.
Dan Slott isn't the first person to figure this out, and Spider-man had numerous writers explore this before he got on board. He's just acknowledging the obvious. Spider-man "being his best self" and Peter sabotaging himself aren't concepts that counter act each other. Peter's quit being Spiderman more than once because he hates how badly it messes with his life. There's far more to Spider-man than Slott's opinions, he's just a recent title holder.Dan Slott in his interviews and elsewhere certainly came up with the concept that "saving people is self-sabotage", you can definitely see that wrong notion and poor concept infect his run. He called Spider-Man self-destructive numerous times and in many stories and issues completely misreads the point of Amazing Fantasy #15, namely that being Spider-Man is Peter being his best self. He's a better person for being Spider-Man the superhero. Slott's also responsible for word misue and poor understanding of concepts to justify his take.
