This. ^^^^^ That’s my understanding too. “Thou shalt not kill” cannot be the intent, otherwise soldiers doing duty in war are committing mortal sins. Self defense would not be possible, and mercy killing would be wrong which can be debated but some would say it would be immoral not to put a person out of their misery like we do dogs. Also capital punishment would not be allowed, also debatable but legal in many states and not forbidden in any major religion except Buddhism.

I was taught that the commandment "Thou shall not kill" was a misinterpretation in the King James version that should have read "Thou shall not commit murder".  There is a difference.

It occurs to me that my question may be a bit abstract, so I will try and illustrate with an example. I will try and answer the proper moral response from a Christian pacifist perspective (I am not an expert on such a perspective by any means though.)

One of the Ten Commandments is “thou shall not kill”. Therefore one is not justified in killing the prior attacker even with current threats or at any other time.

Seems a simple and clear deduction from that perspective.

She may have said within and I didn’t hear the “with” part because I am deaf as a post. I also kept wondering why Ben Shapiro was talking about Trump dropping bunker busters on Florida.
