and you’re not hurting anyone else in doing so

Evaluating this condition across all levels of your community is almost impossible, from the individual level up to a global level. It can also be evaluated across time. The total sum effects of actions (and inactions) are incalculable.

Of course, even if it was calculable its not objective because "hurting or harm" is are subjective terms. I wasn't trying to start a treatise on the validity of Kantianism vs Bentham utilitarianism.

The best we can do as adults is adopt a philosophy of "least harm" which is subjective to the actor, and then act in accordance with that philosophy. We alter our philosophies based upon experience and additional information. The additive nature could mean on our deathbed we discover we were the hero, the villain, or a pure non-entitity. Welcome to the ambiguity of adulthood. Do your best, however you define that.

That's what the Good Place touched on, but wasn't confident enough to say outright without being cancelled: There is no ethical existence under capitalism. But we can all live as ethically as we can in our own lives. Focus on the lives you can directly impact, and don't turn a blind eye to the indirect suffering of others even if there's nothing you can realistically do about it.

that is my take on original sin

wills compete for value. lives compete for resources. either way there will be strife.
