I've heard of Varg Vikernes being described as the "Kurt Cobain" of black metal, and that's true to an extent. He's an overrated, self-absorbed jackoff. And, while he IS talented, he gets way more credit than he deserves. His proficiency on guitar was not immense, though he did posses excellent song-crafting ability. His vocals were horrendous, so much so that I really can't listen to Burzum very often. Despite my criticisms, Det Som Engang Var (or something like that) was a great album, but c'mon - I can think of about a dozen black metal musicians better than Varg. Ihshan, Galder, Fenriz, Satyr, Oystien Brum, ect., ect.
The fact that he is a murder means nothing to me, because to me murder is a crime that is villefied to the point of absurdity. Yes, the killing of the (relatively) innocent (children especially) is unacceptable, but Varg had reason to believe Euronymous was conspriring to kill him. And though Faust killing a gay guy for hitting on him was excessive, overall, I don't see murder as something to hate someone for - especially when the victim is someone you've never met/known.
The fact that he is a facist/racist is also something that stirs no emotion in me either. I am personally accepting of other races/cultures, but I defend anyone's right to have a supremacist world view. I may disagree, and think one is an imbecile for such beliefs, but to prevent that behavior is destroy liberty as we know it, and that is something I will never be a part of.
So, to summarize, I don't really give 2 shits if Varg runs free or is left to rot.
