Assuming you correct in your assessment (and I don't believe you are), that doesn't make it right.
Ultimately the whole purpose of government, indeed its only legitimate function when you strip away all the frou frou and look at its core, is to preserve and protect innocent life.
Government can breach that fundamental duty two ways: 1) by using its own agents to murder innocent citizens, or 2) allowing private agents to murder innocent citizens.
"Ultimately the whole purpose of government, indeed its only legitimate function when you strip away all the frou frou and look at its core, is to preserve and protect innocent life."
Indeed, as Reagan put it long ago in a Reason Magazine interview:
REASON: Governor, could you give us some examples of what you would consider to be proper functions of government?
REAGAN: Well, the first and most important thing is that government exists to protect us from each other. Government exists, of course, for the defense of the nation, and for the defense of the rights of the individual.

(The right to life being the most important "right[] of the individual" IMHO.)
