Here are a few rules for what might be a moral life, for those who can or are willing to comprehend them.
One should knowingly, do no harm to another.
One should avoid doing anything that may harm another later.
If one must do harm to another, one should make every effort to minimise that harm.
Self harm should be discouraged, because it indirectly harms others.
A lack of foresight is harmful.
To violate these rules is to loose the protection of them.
Unfortunately to apply these rules get complex incredibly quickly and requires a massive amount of thought.
