I know! Same when Vexen dies and says he doesn't want to.
Nomura confuses me.
Okay let's say it's an instinct
Just to fill in the holes.
The only one i see without emotions is Saix.

nobodies have feelings, there just weak and no one knows about it (or so they act/pretend)

 

[MyLegacy]

maybe nobodies are actually reincarnations with little strength in their hearts so cant emulate emotions as well as others o.0

Nobodies don't have hearts. It's been explained that they act upon their memories of having one, and pretend to feel by using those memories of having emotions.
