I kind of find it hard to believe a person like I'on would accept killing innocents who were just doing their jobs... He is smaller, but also stockier and can always just hit the vampire over his head with his staff, no? Since Morgan is a vampire, there is probably a somewhat smaller chance that he'd be permanently brain-damaged from it. (Well ... there'd be quite a bit of explaining to do afterwards, but at least people'd not be dead. NPCs are persons, too, and shouldn't treated any differently IC than played characters.)
