even a fighter-class in morrowind could steal. this is how it goes when I do it:
Aelya: *makes sure no guards are watching....Picks the lock on a house....Goes inside...sucks up real bad to whoever is inside so they think we are friends...starts to taunt them till they attack aelya...*
owner of house: *gets pissed off and attacks aelya with nothing but fists for weapons and cotton clothing as armor....starts screaming things like, \"now you die!\"...*
Aelya: *chops the crap out of the owner with a fiend katana and kills them quickly...loots the body....loots anything of value or usefulness in the house...sells all the useless junk for a few coins...theft complete*
Actually, a good way to robbing almost anyone in morrowind is by making them attack you.
