What kind of mentality is the person who sends threatening text messages from a psychological point of view?

From a psychological point of view, people who send threatening text messages often have no choice but to take care of each other. His mind was in a state of collapse, but he wanted to show a stronger side, so he sent these threatening messages. Moreover, such people often have no legal awareness, because threatening text messages often provide evidence to the other party, and the other party can appeal. Moreover, these people have no legal awareness, and what they do is relatively naive. Naive, they are not very mature, no matter what happens, they should communicate according to normal conditions. If there is a problem, if the other party does not actively cooperate, you can find relevant departments to mediate and help deal with it. These are all examples of lessons that can be learned from the past.
