Cerebus Retardant: For all the dark comedy about the bot having feelings, it's still a giant war machine that has been stupidly allowed to work in an office where the other workers are completely oblivious to the fact he shouldn't be there in the first place, and instead rip on the warbot constantly, making them look like idiots, making everything that happens inherently funny, even if it's supposed to have pathos. These people deserve whatever fucked up things happen to them.
Darkness-Induced Audience Apathy: If you don't subscribe to the Cerebus Retardant theory above, the comic is just an unrelenting parade of suffering and failure. Hard to laugh at.
Squick: The women who went on dates with him only knew 3 things. His name, his age (7) and that he is a robot.
Tear Jerker: Warbot's note from his failed suicide attempt simply read "No love". Unfortunately, due to his lack of manual dexterity, it is practically illegible (especially to his co-workers, who are oblivious to his suffering), and that took him two full days and at least thirty attempts to write.
