Did Thompson provide persuasive evidence that South’s slave system was morally evil? I would say yes.

In the autobiography, Thompson has lots of stories, proof, and evidence that the slave masters were harsh and abusive to the slaves. One of the first examples we get was when a slave child dropped and broke a plate by accident, and they were punished by getting whipped, which resulted in a pool of blood at the child’s feet.

Now that’s a big overreaction, assuming that the plate wasn’t anything special. Even if it was well-prized, it really didn’t need to result in a puddle of blood. That was definitely harsh, abusive, and wrong. This kind of whipping for such little reason was so harsh to slaves, that some literally mentioned that they would rather die than get whipped one more time.

some more proof is that the slave masters would whip their slaves every week for no reason at all, other than the fact that they would appear to become more powerful. Whipping for little reason is harsh enough, but whipping for the reason to have your slaves fear you? That’s all the more worse.
