Alduin is a Nordic corruption of Aka, he is supposed to be evil.

Daedra are also evil, almost fitting the definition perfectly nounnoun: evil1.profound immorality, wickedness, and depravity, especially when regarded as a supernatural force. The relativity of the term "evil" really doesn't mean much, obviously the Daedra don't consider themselves evil (very few evil people do) but they simply are.
