Yes, but it's a little worse than that. One might take that to mean environmental, congenital, or even genetic factors. But there's more. Consider the role that trauma has to play here as it can directly cause arrested psychological development:
That was really interesting. I had a friend who's brother killed himself when he was a young teen. If things didn't go his way or he was overly irritated, especially when he was drunk, he reacted by destroying things like a pubescent boy might. He also came from a wealthy family so I always thought that contributed as well, like not caring if he breaks something just buy a new one. But he didn't just break his own things. I had to end the friendship when he drunkenly threatened a woman who lived in my building with a gun. I hope he's ok.
Sorry to hear about your friend. While I'm no doctor, that seems to fit the bill to me. I've known people that had other trauma when young, and yeah, maintaining healthy relationships seems to be the hardest thing for them. Your story reminded me of a lot.
