I do not mean any ill either for the record, however I know some gulf war vets that were threatened with article 15 or court marshal if they had brought some things home. That is what I refer to.
BUT
Here in this game, we are playing a FANTASY role playing game! so, Sheldon will collect everything - weapons and armor of the fallen enemies can be used to equip mew recruits.
Which was again my point. If these were simple mercenaries, or humans (ok or demihumans) forced, coerced or even seduced into the service of evil your qualms would be well placed. And such is the nature in real life. Since we are dealing with ultimate evil we can in these cases act without regard to questions of morality, but act with impunity as far as executions (so long as they don't surrender - but would a demon surrender?) as well as any goods such evil possesses.
