What happens to a character with no soul?

[Siege Tower]

I'm currently making a character that had previously had their soul completely removed by an incubus. I'm wondering what consequences this character would have from the lack of a soul. Despite the obvious things that happen (or don't happen) when they die.

I'm wondering if things like divine magic would be extra effective on them or possibly do nothing at all. Maybe animals naturally dislike this character? I usually play 3.5 so do any gods ever interact with these kinds of characters in a specific way?

I'm thinking of making this character as lecherous and sinful as possible. Since they have no soul they have nothing to taint.
