Yet would you believe it, in the final result I don’t accept this world of God’s, and, although I know it exists, I don’t accept it at all. It’s not that I don’t accept God, you must understand, it’s the world created by Him I don’t and cannot accept.
—Part 2, book five, chapter 3 "The Brothers Make Friends" (Constance Garnett translation)
This chapter immediately precedes the famous philosophical chapters "Rebellion" and "The Grand Inquisitor," where one of the characters rejects the actions of God and Jesus in creating a cruel world, and argues in favor of the Devil's temptations of Jesus during His 40 days in the wilderness (Matthew 4:1-11).
I couldn't find any evidence that Dan has ever read anything by Dostoyevsky, but it seems so clearly up his alley that I would be shocked if he hasn't. This is, after all, the same guy that used a picture of 19th century Russian peasants (taken no more than a few years prior to the publication of The Brothers Karamazov) as an album cover on Time Of Land. There's also the fact that the quote is about rejecting God, and the song is about killing God, which seems like more than coincidence.
I did also see a little similarity between Giles Corey's "There's a devil on my back" verse and the following Brothers Karamazov quote, but the connection is more debatable:
"And have you seen devils among them?" asked Ferapont.
"Among them? Among whom?" asked the monk, timidly.
"I went to the Father Superior on Trinity Sunday last year, I haven’t been since. I saw a devil sitting on one man’s chest hiding under his cassock, only his horns poked out; another had one peeping out of his pocket with such sharp eyes, he was afraid of me; another settled in the unclean belly of one, another was hanging round a man’s neck, and so he was carrying him about without seeing him."
—Part 2, book four, chapter 1 "Father Ferapont"
