"But Jazzy, what about when you're on the other end??" that would suck, yes. But would it be worse overall? Bad people would be fucking afraid, because they don't know where it's going to come from or when. Crazy people gonna crazy and so it makes no difference to them, but all the lowlevel dirtbags would be scared stiff, unable to make moves against others, and isn't that a good thing?
Narcissists, when afraid snap immediately into behaving properly, they are polite, they are submissive, because they are afraid
Psychopaths, however, do not get afraid, they only get angrier, and angrier.
Crazy gonna crazy so don't count them as a data point
