This might be off topic, but in the spirit of "Rewriting" I think making Shar basically just "EviL' just cuz is a terrible writing choice, or whatever...
When I was first playing the game and having Shar and her followers being described, it felt mostly like they were the misunderstood and outcasts for "some reason" or another, So i had it in my head they were just basically Anti-Hero/Anti-Villain-ish or along those lines. So what I'm trying to say is I'd rather Shar etc be rewritten to fit that mold more.
