I usually take the "good" path when doing quests, although one thing I like is that this game isn't that clear what the "good" path is, like Folo and his pigs.

But recently, I went for a full-on totally evil playthrough, and here are my thoughts:

Your tears nourish me.

The evil path also has some really awesome dialogue.

"Killing Seekers is so much fun it ought to be illegal!" "It is!"
"I'm not going through all that trouble. Eternity can't last that long."
"You certainly have a novel way of giving head."
"Oh come on, you have to admit that was funny!" "Are our lives just something to throw away for your amusement? You're mad, Dragon Knight!"
