Splitting hairs, but I'm not asking if such an argument would be persuasive, I'm asking if there is such an argument that would be logically sound. If morality is a social construct, as I accept the consequences society provides, is there a logical reason not to kill? Or maybe I should ask, if you somehow decided that you wanted to kill someone more than you cared about society's consequences, is there a logically sound reason for you not to?
Note: I'm not saying you would ever reach that point, or implying anything but that I want to see a logically sound reason for restraining yourself.
To go into formal logic for a moment: If you accept the axiom that committing a murder is acceptable, then there cannot be any way to logically argue that the axiom is wrong--it's an axiom. There are no propositions you can make, or conclusions you can reach, that can flip that axiom, because you can't do that to axioms.
So basically, the answer you're looking for is "no." If you accept that murder is okay, then there is no way to convince you that it's not.
