Can someone elaborate on the thieves guild and the spectrum of morality it covers without spoiling major plot points if at all possible. I am not expecting to be running around saving kittens from trees, but even after just the initial quest where you act as this thug extorting money from the people of riften, I felt like a complete tool and not like swashbuckling style thief.
If i am completely off base and they really are more free spirited and kind but I just need to get into it then I would like to know, at the same time if they really remain a bunch of heartless and greedy thugs then I would also like to know that.

And, yes, they are kind of a syndicate.
