The Aedra represent creation and stasis, the Daedra represent change. It's simply how they are, naturally something that exists to change things will meddle more than something that creates and then leaves alone.

Also, daedra are not necessarily evil. Mortals may perceive them as such, but this is not really true, any more so than a forest fire is evil. They simply are.
