Actually, YOU CAN kill your son!
13:6 - 13:10
If thy brother, the son of thy mother, or thy son, or thy daughter, or the wife of thy bosom, or thy friend, which is as thine own soul, entice thee secretly, saying, Let us go and serve other gods, which thou hast not known, thou, nor thy fathers;
13:7 Namely, of the gods of the people which are round about you, nigh unto thee, or far off from thee, from the one end of the earth even unto the other end of the earth;
13:8 Thou shalt not consent unto him, nor hearken unto him; neither shall thine eye pity him, neither shalt thou spare, neither shalt thou conceal him:
13:9 But thou shalt surely kill him; thine hand shall be first upon him to put him to death, and afterwards the hand of all the people.
13:10 And thou shalt stone him with stones, that he die; because he hath sought to thrust thee away from the LORD thy God, which brought thee out of the land of Egypt, from the house of bondage.
Deuteronomy, Chapter 21:18, the Bible says:
If a man has a stubborn and rebellious son who does not obey his father and mother and will not listen to them when they discipline him, his father and mother shall take hold of him and bring him to the elders at the gate of his town. They shall say to the elders, "This son of ours is stubborn and rebellious. He will not obey us. He is a profligate and a drunkard." Then all the men of his town shall stone him to death. You must purge the evil from among you. All Israel will hear of it and be afraid.
