There are some things that need to be socialized in my opinion. Things like what the population needs as a whole on a constant basis. Utilities, medical care, and the like. Basic needs being fulfilled so of thing. Extra stuff like entertainment, toys, luxuries, and the like should be held privately in a competitive market for they aren't needed for basic human living.
Also murder is defined as a killing of an individual unsanctioned by a government. If the government sanctioned the death of those individuals, right or wrong, it wouldn't be murder.
