Is it possible for you? Because all my characters end up as thiefs, taking all the coin and worthy things i find in houses and places i shouldn't be in

Well...I usually take anything that isn't flagged as owned by someone....so yes I can play without being a thief.

I used to be like that in Morrowind. Robbing people blind in their sleep. I broke free of the spell by starting a paladin-esque character with strictly enforced RP standards. It was long ago but it teached me a valuable lesson and I'm able to enjoy the games alot more now.

Most of my characters are at least quite law abiding, and not stealing ordinary things is very easy. There are a few quests that requires stealing, though (not talking TG here, but sidequests, and CW). In some cases it's easy to motivate it being for a greater good, in some cases it would mean you must not do that particular sidequest.

I have a hard time becoming a thief. None of my characters has been one (though one completed the thieves guild quest, still without stealing much!) I started one whom I intended to become a thief; she broke into two houses and pickpocketed one person and slaughtered a chicken... then I found she was doing a lot of fetch-quests for random people, but I doubt a true thief would do that, so I ended her.

I almost never steal anything haha. It doesn't even occur to me. Apparently, I'm too nice.

I can't, I've been doing this since I first discovered the series and the freedom to steal, I can't help it. it's quite addictive. No matter what sort of character I play, they all steal more or less what they need.

I've probably stolen about 20 things in my 100+ hr playthrough.
