I see it more as a depressed cynic who is condemning God whilst at the same time hating himself. The narrator is asking to be God's murderer because 1) God is a violent and cruel deity (this resulting from loss no doubt) and 2) The narrator is no better, hating himself and therefore willing to go along with murder and cruelty in God's name. All of this is done with a very sneering, accusing tone. The narrator, probably once religious, has since turned from the divine while also turning on himself. I see this as a reaction to the cruelty of events and coldness of humans. Existence is bleak.
