Such a person does not walk the world today. Everyone falls short of this mark every day. For example, a person campaigning for a political office admits wrongdoing in the past and says he will not do that again.
Most people accept that commitment.
He is elected. Thereafter, he repeats this wrongdoing and he is confronted again. He takes steps to cover up this wrongdoing by using his workers and his friends. He lies under oath in a lawsuit which is very important to the person he is alleged to have harmed. Linguistic contortions with the words used cannot legitimately conceal a lie, or if under oath, perjury.
