Okay I agree with the idea of a rotten system as think that generally many legal or government institutions are rotten and self serving for the rich.
But the flaw in the argument from my perspective is that if all the decent people don’t go into the police, the ones with integrity, a moral compass who genuinely try to help people and do the right thing, then that leaves the bad apples.
So for going into a system and hoping to change it for the better, help/protect their community from criminals and the bad apples and make a real difference in lives, by that logic those people striving for better are still bastards and that just doesn’t feel right to me.
