There are problems either way. If the fine is proportional to psychological harm, it punishes the victims who admit to having a thick skin. If the fine is not proportional to psychological harm, it makes bullying the most sensitive people too cheap. As an analogy, consider physical harm. We would probably agree that the punishment for slapping someone should be smaller than the punishment for murdering someone. However, what happens if someone is so exceptionally fragile that if someone slaps them, they literally die? What punishment should we apply? If you say "the punishment for murder", the accused will feel that this is unfair. But if you say "the punishment for slapping", then it means that if you know that someone is fragile like this, you can practically murder them for free.
