"Kill them all. God will know His own.". This was a misunderstood reference to 2 Tim. 2:19 which in part reads, "The Lord knoweth them that are his". I think this comes from around 1210AD, when Pope Innocent III unleashed "orders of fire and sword" against heretics throughout Europe. In this process there was a terrible massacre at the city Beziers, where it was thought that over 100,000 people were killed. After that city where taken, they had captured over 450 heretics, most claimed to be good Catholics. The quote is believed to be first used here, when they killed all the "heretics". It did not matter if they killed good people, because if one led a godly life, God would know of it, and the reward would be eternal paradise anyway.

Deuteronomy 21 Verses 18 - 21
If a man have a stubborn and rebellious son, which will not obey the voice of his father, or the voice of his mother, and that, when they have chastened him, will not hearken unto them Then shall his father and his mother lay hold on him, and bring him out unto the elders of his city, and unto the gate of his place And they shall say unto the elders of his city, This our son is stubborn and rebellious, he will not obey our voice; he is a glutton, and a drunkard And all the men of his city shall stone him with stones, that he die: so shalt thou put evil away from among you; and all Israel shall hear, and fear.


There are many more, and many more violent. That does not sound good.

Interviewer:- Shooting! That's a bit irresponsible isn't it?

Jones:- I don't see why, they'll be properly supervised on the range.

Interviewer:- Don't you admit that this is a terribly dangerous activity to be teaching children?
You're equipping them to become violent killers.

Jones:- Well, you're equipped to be a prostitute but you're not one are you?
