We all morally fail all the time. It's ok because we are fallible beings with limited access to information about the happenings around us. Asserting that we are capable of perfection as a core tenet only leads to a cynical disappointment-cum-misanthropy.

This means that morality consists of recognizing your responsibility to comprehending where you are in the causal DAG and what the probable outcomes of your actions might be, without shaming yourself about what you did before you understood.

It's not a perfect description because "getting paid not to understand X" is a real thing, but it's a start.
