If I'm not really into the show after watching the first two episodes, should I drop it? Is there a good reason that he spared the witch kid's life in episode 2? I'm assuming there is a justifiable reason for killing witches and their guardians(evil?), but I would think that this also means that the kid is going to grow up into an evil witch.

I'm not a big fan of the comedy so far since it makes it very difficult to take any of the fights seriously.
