I did come across a very interesting quote in the book that I'm reading - Memory of Fire by Holly Lisle:
Console yourself not with the lie that your foe is weak, or stupid, or evil. Sometimes the enemy is worthy. Sometimes his cause is just. Sometimes both sides are right in their own ways — and in the hour that just causes collide, good men will rise up and leap into the fray, and the clash of their meeting wil shake the heavens. And their blood will flow like rivers.
