People! Humans! Literate beings! Anyone! I am calling you!

Is there anyone around (or am I a hopeless lone freak) seeing that one's moral code (ethics, morality, whatnot) is not the one and the only? And that every single scoundrel one may see, just follows their scoundrelly morality (knowingly or not)? And that acknowledging it has exactly no impact on out decision to counter them?

I am fed up and scared of people who have access to any kind of ultimate truth. Especially, when they seem to be my allies.
