Does anyone else feel that this game unfortunately doesn't really give you the ability to be decent. There's just too many quests IMO where i'm forced to sacrifice people, steal from the good, kill decent people, etc..
Now I understand that I can simply not do these quests but as a player you kind of lose out by doing so. My options seem to be either take the quests and be rewarded for being evil or not do the quest and miss out on content. It would be much more interesting if the game were to allow more options where you can refuse to do things like these and deal with whatever consequences there are with the quest giver.
For instance, the quest to kill the orphanage person. Yeah, I did it but felt lousy doing so. But that's fine that's on me.
But once I did so and then rested I met whatshername from the Dark Brotherhood and was ordered to kill one of three people. Again, I did do but felt really dirty in doing it. Now after the fact I find that I could have killed the assassin instead. Its a shame that I can't still turn on the Dark Brotherhood. I mean, maybe I can and I haven't gone far in enough yet but i'm at the point with them where they want to give me jobs to kill people and I just don't want to do them. Am I going to miss out on a lot of interesting story line just because I choose not to be a cold hearted killer?
and then there's the thieve's Guild questline where I have to track down Mercer. Part of doing so involves my having to become a Nightengale which involves my pledging my life and soul to some deity named Nocturnal. Um, what? I know that this is only a game but what if I don't want to pledge my soul? Well, no story for me it seems?
anyone else having any moral problems?

I know it's just a game, but I feel it says a lot about us how we act in these games (I'm gonna' get some reactions from that statement.
) because our game actions bring out something that's in us somewhere.
Just like you can only blame so much on "just doing my job" there's only so much you can attribute to being "fantasy".
