I'm not sure I see what you mean with this. Your idea is that if one devours enough souls, one gets caught and tortured to death, or something equivalent?
If so, that honestly sounds a lot more simplistic and a lot less gameplay-enhancing than any of the suggestions, so far. It could probably be good in a roguelike or something more in the vein of "choose your own adventure", but if DOS is any indication, that is not what Larian are aiming for with DOS2.
