Well, let me ask this, what does the soul really do? We have the heart that pumps blood through our body and is obviously a necessity to survive (also a delicacy in this game for some odd reason); we have the brain which controls our body's actions and thoughts, and is pretty much the storage unit of everything we are as a whole when it comes to personality and our overall "being". In PS, where does the soul fit in exactly, and how would magic and immortality come into direct influence with this soul and your own body, when it may in fact just be the body that dictates when we die and what happens when we die? If you bind your soul to a crystal, that doesn't really explain how your body would suddenly stop aging (and that also goes in real life when you say your soul goes to heaven, since the vagueness begins with that line - is our soul wearing clothes? How old are we? What's our personality like compared to how it was when our soul was in our body? Does the soul look the same as our body?). The only difference between real life souls and PS souls, is that the souls in PS are playing a somewhat important part in each character's existence, seeing as we can bind them to a crystal and become immortal, or see into/kill a soul in someone's body (I believe I remember reading where there are spells powerful enough to rip someone's soul from their body, which would instantly kill them).
So when I say that it "isn't appropriate" to have souls in the game, I'm really trying to understand what the soul is supposed to do in this game in regards to life and death, and see if I can get a detailed explanation to work its way out of this thread as to what having gods would have to do with having a soul.
And no, if someone wants to lock this thread, I'm not discussing religion, I'm discussing an aspect of the game that might cause a huge inconsistency later on if it isn't pointed out.
