I have a very hero oriented personality, so it really bugs me how I have unwillingly been forced to pick up 3-4 quests that are now sitting in my quest list to either murder or rob certain individuals. When talking to people who I soon found out were bad, they asked me if I wanted to participate in little "ventures" that I could instantly tell were of a no good sort, so I declined, but then all that happened was they mocked me for being self righteous and gave me the dang quests anyway. So now I'm stuck with bad guy quests on my white knight of a character, am I really gonna have to do these?

Just because a quest is in your log doesn't mean you have to do it. But I do agree, there are some quests I wish one of my characters could cancel as well because I know he will never do those.

I know I don't actually have to do them, but it drives me insane seeing them there and knowing they're gonna plague my list forever.

Get used to it, like Oblivion, Skyrim is all about doing. There is no satisfying way to walk away from any quests and no repercussions for ever doing so. It is like they only 1/2 did the quests
