Does Armpit have integrity?

I think that Armpit can be true to people if he knows that they can be true to him. But he can also do them wrong like you know that he wont rat on any body like on his book he just kept telling them a different story about how he got the ticks. But he’ll crake sooner or latter if he doesn’t have anything else to say about how he got his ticks then he’ll maybe tell them what happened but if he does he’ll blame it on him self he wouldn’t rat on anybody else but him self.
