To my understanding, it's Hermetic tradition that makes the distinction between the soul (which is a rather central subjective experience) and the spirit (which is associated with the soul, but more like... a determiner of the life events from a wider perspective than the personal-subjective?) And both are different from the ego, which is just our standpoint in the corporeal world.
Christian mythology, especially the folk practice, has this idea whereby a person's soul goes to or "belongs to" either God in Heaven or the Devil in Hell, or nobody in Limbo if you're like an unbaptized baby that died without actually sinning or something. But I think that's just written up by a bunch of medieval monks that thought it sounded cool, and poets/writers like Goethe (who wrote Faust, which is about this thing happening, the selling of the soul) just rolled with it.
There's an interesting episode of The Simpsons where Bart Simpson wrote "Bart's soul" down on a piece of paper and sold that, but the conventional tropes of soullessness like the inability to laugh or mist up a glass with your breath started to happen, and then his sister Lisa got the piece of paper back when she saw him praying and lectured something about Buddhism... where the soul is awareness, so we're ALL soulless actually because we're usually unaware of our place in the universe. Of course, The Simpsons is fiction, so even somebody who wrote "(insert name here)'s soul" and sold it, probably wouldn't have those effects because--you know, science, you're still going to have humidity in your exhale, you're still going to cast a shadow and look in the mirror to pop zits or shave or whatever. That's just biology and physics.
But so, you see, between Hermeticism, Buddhism, and Christian folklore, there are too many definitions of the soul for anybody to really be sure that it even exists. We can consider the soul figuratively, like the emotional effect of having your personal boundaries violated on a regular basis can be considered "soul sucking", or artistic expression that validates a worldview that you didn't even consciously know you had--that artistic work can be considered "soulful".
