Never new about that select option.Probably because I never tried it.
Anyway,could you roleplay dieing from an infiltrator,religious fanatics or in battle as nonhero character, even though there are no game mechanics for this?
Best thing to do for this is to post a RP just before you delete for this. Those RP's sound fine so long as you don't implicate another noble in the death without their permission, standard RP etiquette.
