Nihilism is good because when you don't give a shit, then you don't end up in the absurdity of other people's lives.
For example: competition; if you don't give a shit the other person is actually running alone to get somewhere because they are threaten by you. This can lead to their downfall and I find that very entertaining. if they did won, its highlarious how actually doing nothing and having no meaning can actually cause a chain of reactions.
Second example: everyone is so scared of death they are willing to fight to the death just to prove a point on who's more "right" about the after life. Well, those people are dead, I have no idea what's going on but it seemed hella pointless. But, what the hell do I know? I'm the one still living.
