"Where the Cat and Wolf Play" choice (spoilers)

What choice did you make in that quest, did you kill the Cat school witcher or spare him? I always choose to spare him because I honestly can't blame him for what happened, especially after learning all the details and seeing that the village chief was living fairly well. Instead of paying him the price they'd agreed to, they tried to kill him...they tried to murder someone who just killed a beast they hadn't been able to handle. Not terribly bright. It's a shame the entire village (save for the little girl) were killed in his rage, but the letter you find in his hideout makes his story even more tragic...

I love these side quests and moral conundrums.

Edit: Seven years later and some of you folks are still coming across this post and discussing this side quest. I'm really glad for that, even with the disagreements in the comments, it's all civil! I'm so glad we all still love and enjoy this game!
