There is no sin in killing. See... you go on about all this without even thinking. Fact. God killed and kills folk. If killing is a sin then God is a sinner. Fact: Jesus will kill a boat load when He returns. If killing is a sin then Jesus no longer remains perfect and will on that day enter into sin.
FACT: Killing is not a sin. Murder is a sin. Killing with evil motive and intent and or malice... that is a sin. Killing... in and of itself is no sin at all. If it was then God told Noah, Moses, David, Sampson, etc. to sin. If that is the case then the Bible just became a lie because God tempts no man to sin.
Ponder it... maybe it will make some sense.
