Moral justification for the execution of criminals of war?

[bennyboy]

I don't think "agreement not to kill each other" need apply when one party clearly hasn't gotten the memo. It's pretty simple-- you deprive a kid of life, you lose yours. Of course, because we're so "genteel," we will extend to these POS luxuries their victims don't get, like a trial.

Well, it does apply whether you like it or not.

In my opinion, sheltering someone that evil is itself an evil, and shows a weakness of character rather than strength of one.

Then your opinion is a poor one

You seem not to understand how debate works.  You can't delcare by fiat that I'm wrong-- you must demonstrate me to be so with rational arguments.  WHY do you think sheltering evil is good?  WHY do you think murderers should be protected by the social contract which they have violated?
