In contrast to Tom’s make-believe gang of children, the gang Jim and Huck encounters on the doomed steamboat are very real, vicious, and murderous—but, like Tom’s Gang, this one is just as arbitrary in its moral code. It is ironic that one of the thieves refuses to shoot a man, but is willing to let a man drown. This thief seems to want to excuse himself from the guilt of murder, even though his action here has the same effect as murder. His rule is absurd.
