Sin by omission

France

An old Frenchman enters the confessional and says to the priest:
— During the war I hid a young Jewish woman in the attic of my house to prevent the German soldiers transport her to a concentration camp.
The priest answers
— There is nothing to confess, you've saved the life of this young woman.
The old French say:
— I must admit that in exchange she was doing me blowjobs.
The cure replies:
— I see your gesture was less beautiful but the Lord forgives you. I'm sure that this young woman is grateful to you in spite of everything.
And the old French asks the priest:
— Do you think I should tell her that the war is over?
