A hypocrite is better than a real villain. The hypocrite is from the complete works of Tao Xingzhi.

A hypocrite is more harmful than a real villain, because the words of a real villain can make people avoid it, while a hypocrite appears as a gentleman and does all kinds of evil deeds, which is difficult to distinguish. Tao Xingzhi marveled: "The real villain's suffering is not more than a few generations, but shallow and harmful;" Hypocrites directly lead to false family voices, false national customs, false secularism, and it never rains but pours. "

But this sentence is a popular usage, which was summarized by the ancients long before Tao.
