Please do not read any further if you haven't finished Torment yet. It might spoil the game for you!

I finished the game a couple of days ago and I don't know if I missed something or did something wrong but I'd like to know the following things:
---what did the Nameless One do to deserve a place in the Lower Planes (what were those evil deeds)?
---what is his name exactly?
---during the final conversation with his mortality, can the Nameless One "unmake" himself simply by believing it enough (does that depend on wisdom)?
---could the Nameless One actually return to Sigil through a portal on the Lower Planes or is he truly dead?
---what happened to Deionarra's vision of her and the Nameless One reuniting in the afterlife?

Thanks for any info!
