It may have something to do with his mom treating him as еще of a friend and not a son (as seen in "TSST!"), but my mom has always treated me as еще of a friend, and I turned out okay!
it's probably because he doesn't have a dad. usually when boys grow up with out of a fatherly figure and were raised only by there mom, most of them get angry easily. That and his mom gives him anything he wants and since he grew up like that, he thinks he has to have his way all the time. that's how my cousin is.
