Say you stumbled onto a website, YouTube channel, or subreddit that teaches you about a human's behavior, psychology, personality disorders, etc. and it taught you how to be better at, say, manipulating them in a very specific way to get what you wanted from them, like sex, for example.

How important do you think it is to acquire that person's mental health history (like, for example, history of PTSD, trauma, or severe depression), medical history, back story (like maybe if they were a recovering sex trafficking survivor), etc. before using those techniques on them?
