Even with the Ten Commandments, love isn't on there anywhere, and don't kill doesn't come in until number six (and numbers 1-5 are things it says you can be killed for refusing to follow, "Thou shalt not murder" only refers to unlawful murder, and explicitly supports execution for law breaking.)
Here it is commanding you to kill your family if they want to change religions.
From Deuteronomy 13:
"If your very own brother, or your son or daughter, or the wife you love, or your closest friend secretly entices you, saying, “Let us go and worship other gods” (gods that neither you nor your ancestors have known,
7 gods of the peoples around you, whether near or far, from one end of the land to the other),
8 do not yield to them or listen to them. Show them no pity. Do not spare them or shield them.
9 You must certainly put them to death. Your hand must be the first in putting them to death, and then the hands of all the people.
10 Stone them to death, because they tried to turn you away from the Lord your God, who brought you out of Egypt, out of the land of slavery.
11 Then all Israel will hear and be afraid, and no one among you will do such an evil thing again."
