There was certainly reason to suspect murder for hire but Kurt did do this photo shoot for a magazine shortly before his death.
Maybe he was just trying to appear edgy and X-treme.
Which ironically would royally piss Cobain off if you told him that.
BTW, Cobain and Nirvana weren't expressly "political" in their music.
Pretty much Cobain's very depressed thoughts and ideas.
But they did support liberal causes, as stated above.
One of the documentaries showed him to have had a very hosed life from a young age that began with his parents’ divorce. From there he was basically a loner/street rat and got sucked down one bad path after another.
Then the Record industry, once he achieved success with Nirvana, saw an opportunity to create the next Lennon and he balked at the idea and was unable to handle the situations that fame brought. Then there’s all the drugs and his psycho wife...
I feel bad for the guy in the sense that he was handed a bad set of cards. But he chose poorly.
