I can figure what you are saying but maybe I missed something you were trying to convey. Lets put it this way. The soul is always the light (pure), the body is what messes up (temptations- theft, adultery etc etc) because it looks to the outside as you aptly said. The body hungers for things, ownership, status and everything outward forgetting that the soul needs to be taken care of first. ...hence the constant conflict.
ofcourse there is so much more to it but this is all i can says in a couple of lines
