Oh my! What a burden he carries, forced to turn them loose to prevent them attacking just anyone, all he can do is chose who dies, and in doing so, chose who is spared. Gosh this has got too deep into my head. How does he pick who...? What happens to the creatures if something happens to him...? There could be a whole novel in here, of him going through emotional progression coming to terms with the power, at first enjoying it, then hating it, then himself, then acceptance, but in a way, this snapshot works better, because it forces the reader to think about all of that without giving a slant to it.
