Hey, you’ve figured it out. People are bastards. Welcome to reality.
There isn’t anything in the real universe that is fair. Not one goddamned thing. Fairness and Justice are Human concepts.
So yeah, go think about the squid who has sperm injected into her by the male, lays thousands of eggs and maybe one of them lives to adulthood. Or the basic fact that everything that lives (except Humans these days) exists to be eaten by something else.
Well maybe, just maybe, we can work with that whole fairness and justice thing in our own little world. Or not.
