I have used Sadism for a number of NPCs, and psychological sadism is relatively easy to get away with. For example, a 'mean girl' archetype could indulge in Sadism by telling a girl that she slept with that girl's boyfriend in order to hurt her or by telling all of the girl in her school that a particular boy was inadequate in bed in order to hurt him (or visa versa). She would not even need to be telling the truth, she would just have to better at lying than her victim is at detecting lies.

Psychological sadists can also more effectively play the long game than other sadists for maximum pain and suffering. A man could start dating a woman, sleep with her for a few months, and then reveal to her in a family event that he had been cheating on her with her sisters, best friends, or whatever the entire time. During his cheating, he could have been lying to the women he was cheating with, telling them that they were the only one while he slept with their sisters, best friends, or whatever the entire time. It is even better if the women he is cheating with are married, as the final reveal could end up destroying dozens of families.
