The title sets the tone: the people in this poem are hooked on anger the way an addict is hooked on a drug. The opening lines speak as a "we" who carry either God or evil everywhere, as if the two were interchangeable companions, and who secretly crave "the temptations of rage." There is something guilty in that craving. The group calls out "all the bitter names," giving in to the pleasure of fury.
Then the poem narrows to a single "I." The speaker weeps "blue ink" and drafts a letter in sleep, which suggests that even rest is taken over by the urge to write, accuse, or explain. Blue ink could point to sadness as well as to writing itself.
The last two lines are the sharpest. If God becomes a weapon, used to justify anger or violence, the speaker says they "shall never sing." Song stands for gentleness and honesty, and the poem suggests that faith turned into force would silence it. The mood is tense, troubled, and quietly defiant.
