Dibella is a [nastywordforprostitue], Kyne is a berserker, HoonDing crushes everything in his path, and Boethiah is a backstabber.
Talos is pretty nice all things considered. But no one will argue that he is a jerk. A big jerk (damn Bretons!)
I see Talos as more of a force (like HoonDing; actually, I view Talos/Ysmir as an aspect of HoonDing, due to their similar roles in their respective pantheons) that happens to hold the universe together.
Of course, what are you asking is "good"? Tiber/Hjalti? His actions? His godhood? His divine purpose in the metaphysics?
