"What do you want, Blade? Why are you doing this?"
He shrugged, an uncharacteristic action. "There are many evils in the world. I guess I've chosen one for my personal crusade."
"Why such hatred for priests?"
He didn't shrug. He didn't give me a straight answer, either. "If each man picks an evil and attacks it relentlessly, how long can evil persist?"
That was an easy one. Forever. More evil gets done in the name of righteousness than any other way. Few villains think they are villains.
