Genesis 34:31

And they said, Should he deal with our sister as with an harlot? In trying to excuse themselves, the sons of Jacob implied that men would generally have treated their sister as Shechem had done, and that they felt it to be their duty to revenge the wrong. But they passed over his offer of an atonement for his crime and their own terrible guilt. The fact that other men do wrong to us can never excuse our doing wrong in return.
