"Where the hell do people get this Thou shalt not kill CRAP?"
That's a very good question, that I'm having a hard time finding the origin of.
I have my own thoughts on the issue.
And that is; that Satan uses this misinterpretation to protect his minions. What better way to twist the Ten Commandments on a single word,
First read
The Sixth Commandment.
Then read
You shall not murder.
Then read
Killing vs. Murder ...what is the difference, if any?
I may add more reference to this, later if I can find the source.
I think the source will be found in a very early interpretation, but I'm guessing.
