There is literally no disagreement over whether 'unjustified killing' is 'justified'.

In so far as that statement is true it is a tautology akin to saying "Everyone agrees that the not A is not A". If one tries to make it non-tautologous by say referring to specific subclasses of killing, then one is going to run into problems like sociopaths.

There is widespread disagreement over which acts constitute murder.

Yet that's the entire crux of the issue.

"Everyone agrees that ~A is ~A" is not a tautology, any more than "Everyone agrees that second-order logic is sound." is a tautology.

"Unjustified killing" (Murder) is already the intersection of acts which are killing and acts which are not justified. The problem is that different people have different sets of "Acts which are justified" and "Acts which are morally wrong".

I don't think you and JoshuaZ are having a substantive disagreement.
