Blackthorn claims Vikernes planned to murder Euronymous and pressured him into coming along. He claims that, in the summer of 1993, he was almost committed to a mental hospital but fled to Bergen and stayed with Vikernes. Blackthorn said of the murder, "I was neither for nor against it. I didn't give a shit about Øystein". Vikernes, however, claims that he had not planned the killing and that Blackthorn came along to show Euronymous some new guitar riffs. Vikernes called Blackthorn's claims a "defense [...] to make sure I couldn't blame "him" the murder".
