Poisoning, stabbing, and contradictions in university dormitories are constant. Why?

Personally, I feel that there are two reasons why roommates hurt each other in university dormitories. The first reason is that the personality of the victim is not perfect. It's not that I deliberately denigrate the current education system, but it's true that many schools now only want students to study hard and die, instead of teaching them how to be a person.

As a result, many students are not sound enough. When something happens, they don't know how to deal with this problem when they are angry. Even when something happens, they can't even control their emotions, and they will be easily angered. Then, fight with others regardless of the consequences, no matter what the result of the fight is? No matter who you're fighting with.

another reason is that the feelings of roommates in the dormitory are not deep enough. Take the things around me as an example. In the dormitory of my school, the feelings of each dormitory are particularly good.

When conflicts occur, at most, there will be a few red-faced quarrels, but everyone knows to control their emotions. After a while, the two will get back together.
