Yes, BoJack's quote can be pretty scary. He says, "I'm not happy unless I'm miserable. I'm not alive unless I'm dying." This quote highlights the character's self-destructive tendencies and his general unhappiness with life. It can be unsettling to think that someone is so unhappy that they actually seek misery, but unfortunately, this is often the case for people suffering from depression or other mental health issues. If you or someone you know is in a similar situation, it is important to seek professional help.
