The part in the beginning as a Dwarf Noble. You can get 25 gold in the first 20 minutes by selling out your traditions as a Dwarf. And it has zero consequences. Letting a woman die nets you the best bow in the game. Scamming random NPC and lying gets you more money. Pickpocketing grants you items and money. The only "drawback" I have found of this one is that it gives you a fight or two extra in Denerim. ( So the guards come after you in Denerim for you pick pocketing. After you beat the two static fights while traveling there,nothing changes whatsoever. .) Outright killing people like the bandits in Lothering gets you an extra gold or so. While intimidating them to leave gives you absolutely nothing. Doing assassination quests in Denerim grants you extra gold. As will the burglar and pickpocketing quests also from Denerim.
But I am sure there are more instances like these where the decisions you make. Mainly bad or immoral ones have no consequences to them at all.
I only just finished the Mage Circle (The first place I went to after Lothering) so no spoilers please. But is this what I can expect from the rest of the game? Suppose I can just continue to play my character how I want to. But I guess it makes sense when you look at KOTOR. Which basically had the same kind of stuff.
