Have you ever been stuck hold up with people you hate in close quarters.

Yeah. Some of the people murdered their housemates / families.

Another group went back out into the world as things reopened… and killed other people because they had so much built up anger. They also lost all social norms in isolation. Which likely lead to more things that would have ended up as a “fuck you buddie” and instead ended in homicide.

If you have been out in places or driving post COVID you can see how aggressive a subset of people have become.
