8If your hand or your foot causes you to sin, cut it off and throw it away. It is better for you to enter life maimed or crippled than to have two hands or two feet and be thrown into eternal fire.
9And if your eye causes you to sin, gouge it out and throw it away. It is better for you to enter life with one eye than to have two eyes and be thrown into the fire of hell.
If anyone is experiencing anti-social behavior, it makes much more sense to seek professional help to sway that wrong behavior than simply maiming yourself. :-? That does nothing for the person. The wrong has to be addressed before the person is freed from whatever their "sin" is.
