You may well be correct Michael, however in ALL western Christian translations of the bible that I am aware of the 5th (6th) commandment simply states "Thou shalt not kill"

As I said no if's buts or maybes.

The Koran I believe is slightly different in as much as Chapter 17, Verse 33 states "And do not kill the soul which God has made sacred, except in the course of justice. If someone is killed unjustly, We have given his next of kin certain authority. But he should not be excessive in killing, for he will be supported"
