We can just be people. Don't hurt anyone, no one gets a pass to hurt you. Hurt someone, someone gets a pass to hurt you. Just you, not your "brothers". No matter the status of anyone involved.
Severity, intent, and priors must play a factor in the level of returned hurt, but should never end with none, and death should be a last resort, but never completely off the table.
That's the good-faith interpretation of the golden rule. Instead of the popular abuser and enabler (turn the other cheek) interpretations. They both call anyone who dares hold anyone accountable, a hypocrite for supposedly not following the golden rule.
I don't care what story book it's in, or who said it, or when. It's a good rule on it's own merits. Doesn't mean everything that comes form the same source is equally valid.
