I've often found that in games that the morality system does not match up to my own. I often find it arbitrary and sometimes even reversed. The most prominent example for me was in Fallout 3 where you could quite literally buy karma from the two churches. Neither church provided any service to the people of the wasteland, and the church of atom seemed to actively harm them. I found this so repulsive that in almost every play-through I ended up wiping out the entire of both churches.
Then to add cream to this pie of moral corruption, there is a side-quest where you get karma for removing someone from the church (In Rivet City). This along with Tennpenny Tower made me abandon the system except to farm it for endings, and do what I felt was right.
In Oblivion I pretty much became 'evil' because the quests for the two evil groups were so much better and gave a sense of accomplishment. I found the thieves guild to be the true heroes by aiding the poor, protecting the beggars, and generally being helpful in word filled with self-important fighters, aristocratic mages, corrupt officials, and shopkeepers fixing prices. The Dark Brotherhood in turn were secretive, violent and cruel, but were self-aware and followed their moral code consistently; leading me to respect them as opposed to the other factions. I guess that says more about me than the game itself.
