He is just fed up with life and just roasts everything he sees, also if someone says something that he didn’t ask about he says “don’t care + didn’t ask + ratio”. Also nothing will change him and if people be nice he will be even more fed up with life, he cares about no one and hates everyone, he never had happiness and only laughs sarcastically. Also no one can do better comebacks than him. Even how nice you be he will never care. Nothing can change him and I mean NOTHING!
