Slavery was different in the new world since they were not treated as people but as animals and in his home country he knew how slavery worked and how slaves were actually treated as people. He would be a slave at his own home gladly compared to this because he sees the horror around him and the way that the white people are intimidating and completely different from anything he had ever seen.

It's not parody since the action isn't being dramaticized or made ridiculous, nor is it foreshadowing since there's it's not really suggesting that this later incident will happen. It's also not a metaphor since it's not different things being compared or likened to one another.
