The only vice that cannot be forgiven is hypocrisy. The repentance of a hypocrite is itself hypocrisy.

Asleep, nobody is a hypocrite

Religion either makes men wise and virtuous, or it makes them set up false pretenses to both.

He is a hypocrite who professes what he does not believe; not he who does not practice all he wishes or approves

We are not hypocrites in our sleep.
