On the topic of how easy it is to capture foes alive, I do wonder, how Evil is it to not take Subduing Strike and/or Nonlethal Substitution? It really is not much effort at all to always deal nonlethal damage with no penalty. Archers don't even need to spend a feat and can just buy arrows that deal nonlethal damage. You're pretty much intentionally choosing to use lethal force with little to no advantage at that point. Hell, I think coup de gracing a foe the wizard put to sleep is the same action as manacling him.
