By the way, demons thrown into the thick of battle also expend themselves with incredible force; the optimal balance for them is Angels, because
1. They are strong.
2. They can fly and make a quick escape, or rather, spread their wings from hell.
3. They can "heal" themselves on the battlefield.
What are you trying to compare demons to, sometimes with one, sometimes with another? Demons are demons, and they will defeat anyone, even in Africa:)
P.S. Is it from Death that one hears a song for Life?
