Moral justification for the execution of criminals of war?

[Macoleco]

It's actually MORE costly to taxpayers to execute someone than it is to incarcerate them long term. I mean, unless you want to scrap all that pesky, pricey stuff like lawyers, evidence, appeals...you know - 'rights'.

That's not a problem with execution. That's a problem with the execution process. I could (and probably would) take out a convicted child rapist for about $10.

And if we're so big on rights, I would think that a life sentence, being almost as life-ruining as an execution, should be subject to all those same expenses. But we seem pretty comfortable with depriving a (black) man of his liberty until his existence ends if he takes about 3 wrong turns in life.

To get back to the OP: criminals of war. I don't particularly think we NEED justification. If we are lucky enough to win a war, we can string up whomever we want on a pretext-- the purpose of the pretext being to give us an excuse to pat ourselves on the back for our moral virtue more than anything else.

Then in that was it was immoral.
