Anybody else permanently chillpilled from growing up with a dad that rages?

Man is currently retired and has nowhere to be but still can’t help himself. Someone turns a little too slowly? He’s the guy blaring his horn and rolling down the window to verbally assault you. Over the past few years I’ve actually kept track of each car ride with him and there hasn’t been one without some incident. Watching anything on TV with him is insufferable. He’ll find a reason to rage at the most meaningless thing. Jeopardy’s on? He’s decided who he likes and is hurling profanity any time the other two contestants get a correct answer. Not in a joking manner either. Growing up around this has literally chillpilled me for life. I’ve never honked my horn or yelled at anyone. What causes someone to live like this? Why would you choose a life of misery?
