Aggressive angry people were frequently enabled whole their lives. They were not taught to control or suppress anger they were taught everyone else is at fault.
That is frequent real world situation.
Likewise, people who feel wronged and treated unfairly because they are subject to the same rules as others are a thing. Their boundary of "only I matter, you dont" was crossed, but is not legitimate at all.
The typical dynamic is that bully is enabled, because it is easier. And typically victim is pushed to more submission, because it is easier. And bully grows angrier and more aggressive.
And it is the same in politics.
