Mean people

Don't be a jerk. Or you will end up like one of these people. For instance, one of the meanest types of people is that they say mean-spirited sentences like "Nobody cares about you!", "If you don't shut up, I'll kill you!", etc. Which leads them to hurting another person's feelings and the mean person to be disliked/hated even more. That's why the more mean they are, the more hurt the others are, and the more angry the god is whenever he sees the dead mean person's spirit in the afterlife.
