I don't think the discussion of Souls and Spirits really has any relevance here. For a start, how do you define a "soul" or a "spirit", and what's the difference? Secondly, what difference does it make if something has a soul? Surely if something doesn't have a soul, then it's even less right to kill it, because if you kill it, then it's gone, whereas with something that has a soul, at least there is some kind of continuity after death...
