I just think that Courtney needed Kurt a hell of a lot more than he needed her, so why would she kill him? We all know that on her own she sucks. She's a complete mess. At least with him alive she could be "Kurt Cobain's wife".

Any time I saw Kurt do an interview he looked like he was about 7 seconds away from jumping out a window, so I do believe he commited suicide.

Plus, Courtney's not smart enough to pull something like that off. The only time I could see it happening is if they were both high and it was some kind of "Sid and Nancy" thing. We'll never know, I guess.
