For the record, I stated that "it was 3 months down the road and I'd wait and see". I am more than aware of misdirection.
I actually own SPIDER-MAN VS. WOLVERINE #1, where Spider-Man accidentally kills Charlie. She was suicidal after her years on the KGB and wanted to die on her own terms, not their's, and Spider-Man was distraught and frustrated by not only fighting Wolverine (after Wolverine, having been asked to end a woman's life, does what he usually does; oblige, but Spidey interupted and so Wolvie "stabbed" wrong, hurting but not killing Charlie), but by the murder of Led Leeds by assassins (this was before Hobgoblin was embroiled into that bit). Charlie purposefully sneaks up behind Spider-Man after he just barely got out of a stalemate against Wolverine (where the smug X-Man, lucky Spider-Man never attempted to use his webbing against him, had held his knuckles to his neck and dared Spidey to try to strangle him to save himself) and Spider-Man blindly reacted to his "spider-sense", slugging her full force and killing her. He expressed some regret on the plane ride home but NONE of this was expressed anywhere. You would think this would have been some moral crisis for him. But to the best of my knowledge he never told MJ or anyone else about it, and he never emoted about it again. To his credit, I don't recall Wolverine bring it up, either; the only tidbit carried over from this story was Ned Leeds' death and the fact that Logan figured out who Spider-Man was via scent. It actually was a suspenceful dark tale, but I agree more should have come of that accidental homicide.
At the end of the Clone Saga ending REVELATIONS, Spider-Man literally shoves a bag full of lit pumpkin bombs into Green Goblin's chest and sends him hurtling off a rooftop, with no attempt to save him. Lord knows how Norman survived the explosion at all, but he did. Ben Rielly, his foster "brother" had just been killed, but, again, no hay was made of this. No moral introspective, no shock from the supporting cast, nada. Even WIZARD at the time was appalled by the lack of follow-through, and they'd been begging for ANY end to the clone mess for a while.
So, yes, I am aware that May might now die in 3 month's time and it could wind up being a crook, either the sniper or perhaps someone Spidey squeezes too hard. I just hope that if JMS is going to resurrect this plotline of "Spider-Man attempts to kill/kills someone" bit, he actually develops it somewhat. I mean, even Superman has killed people (in an alternate reality, he iced 3 Kryptonians from the Phantom Zone with their world's Kryptonite, seeing no way to outfight them and prevent them from taking over his reality, and as "punishment" for killing everyone on their world's Earth; the stress/guilt drove Kal made, making him don a Guardian costume while he slept). Hopefully better than with Morlun, THE OTHER, and Digger ("Oh, Digger's a zombie, no guilt from killing him").
