At times, Mae'Var will in fact tell you to get your butt over to Lathander's temple and swipe the figurine. This could be either alignment (no idea chaotic or evil scale), or reputation based. Evil chars start off with a naturally lower alignment than LG chars (2pts lower IIRC). However, I have only tried the quest during day-time, and the statue is not on a person but in a safe. The safe is pickable, but you set off an alarm that turns the temple red. Maybe DT, will help you find the alarm, but I doubt it.
You know, you can just tell the guy in Helm's Temple, no, I won't do the quest.
I'll try being nicer if you try being smarter
