People constantly say that humans are terrible by default, selfish, and violent, but BY DEFAULT, if you ARE a well adjusted human being with empathy, you will ALWAYS feel conflicted about committing violence towards another human, even if they 100% deserve it. In fact, if you kill or severely maim someone, you’ll always feel conflicted about it if you are a good human, and doing it several times (or hell, even ONCE if it’s traumatizing enough) will give you severe PTSD. The problem of humans being terrible to each other is always created by indocrination, propaganda, and the fact that being a selfish idiot is rewarded in capitalist society. This is one of the reasons why I think humanity is inherently good, and that evil people are the ACTUAL deviants, who just happen to be rewarded by the way society has been structured for a very long time (even before capitalism).
That’s one of the biggest flaws in utilitarianism, there isn’t really an objective measure of goodness, therefore aspiring to maximize goodness is always flawed.
The alternative moral framework, the categorical imperative postulated by Kant is also flawed, as it’s presupposes a rational human, and most humans don’t act like rational beings.
In the end people are all personally responsible for their actions, and no higher power is keeping score.
If you want a good read on mortality and free will and how the dichotomy between right and wrong is flawed I would suggest this dialog by logician and philosopher Raymund Smullyan who brilliantly catches the flaws in the western boolean approach to morality. It’s a long read, but quite worth it.
