I used to love Brand New back in high school and college. When The Devil and God are Raging Inside Me came out, it pretty much captured my life for months. Turns out that the album's lyrics were a little more.. autobiographical than most people thought, and Jesse Lacy is a shitty person.

Varg killed Euronymous because Euro was talking about making a snuff film of Varg because he (E) was jealous of how much success Varg was having with his own project and activities.
Keep in mind that Euronymous's response to his band's vocalists' suicide was to take a picture of his dead body and collect pieces of his skull to hand out to his friends as necklaces. Out of all the shitty things Varg Virkernes has done in his life, killing Euronymous just about makes up for it.
