You don't get to be a shitty person with the excuse that the world is shitty.

Every human has a moral obligation to be decent and kind to other human beings, that is if you are not a human and an animal with, no morals, often people genuinely act shitty completely uncalled for, because the world is shitty and most people a evil, so "let me be evil first so that no one can hurt me"

This is a dumb nihilistic pov and needs to be ended. Because you have trust issues you choose to give everyone else trust issues.
