Why is Sune Chaotic Good?

[Tanarii]

Sune believes in pleasure for all. Fostering beauty in the word. Creating art and investing in long distance trade. Beauty is more than just skin deep, it reflects the core of a being, fair or foul. And romance, true love winning over all, and following one's heart to one's true destination.

In particularly, the beauty is not just skin deep but comes from being a good person as opposed to a bad person, would be a core belief that would mark her as necessarily a good deity, I'd think.
