Musk has problems with impulse control. That's why he publicly called a literal hero of dying children a "pedophile". If he didn't have money he would likely not be able to keep friendships functional, because he doesn't know how to interact with other people in a healthy way.

I don't understand how you can look at his public behavior and think anything else. The only alternative is that he thought doing shitty things was a rational way to improve his situation, and I personally think that's a worse option
