Answer: Boredom is not a common reason.
Step-by-step explanation:
I don’t think being bored is the most common reason for people’s bad behaviour. Sure they can use it as an excuse when the main reason behind their actions are much more deeper but they don’t want others to know about it.
However, I think people do bad things out of emotional damage, heavy resentment, anxiety leading them to bad decisions or just a psychiatric condition. On this case, I think the last option is the one that suits best.
