I get your point about Peter becoming "evil" because of Venom, but you should remember the new information we learnt about Venom in the last years. Venom wasn't essentially a bad guy then, but it got corrupted by the way his first host (Tel-Kar, the Kree super-soldier). So, all things considered, I suppose the only way to avoid Venom's influence to make Spider-Man violent can't be avoided unless we get a story where Spider-Man was the FIRST host.
Yeah, and there was quite a scene after MJ said that. Unexpectadly, Felicia appeared, which made Mary Jane leave; yet when Felicia was about to leave, the symbiote stopped her. Felicia thought this meant she was more important for Spidey than Mary Jane. So yeah, I'm quite intrigued about how Mary Jane and the Black will get involved in this story. (Although I have some "twisted" ideas".
