>Many very dishonest people help themselves sleep at night by pretending that being polite excuses their actions.
Dishonest people don't excuse their actions by being polite, they excuse by way of a defence which justifies their behaviour erroneously (i.e. those rules don't apply to me because...).
Dishonest people being polite is just a way of manipulating targets. Them not being polite doesn't stop them from being dishonest, it just removes a tool from their toolbox.
Keep it kind that it's easy to tell if somebody is impolite, but much harder to gauge whether they are dishonest.
