From my perspective, your post exemplifies why. Are the soft-spoken women you know are also murderers who commited countless atrocities? Because this is who Arueshalae is. She is basically a serial killer who has found faith through a deux ex machina intervention. She has murderered, tortured, worked in the arena and the demonic brothel; I recall one of the slavers praises her as a "valued customer" in the demonic slave markets... how many evils has she committed in the centuries of her existence as a demon? Yet you, just the same as writers, reduce this character to a "soft spoken female". As you wrote before, you don't care about inconsistencies in the characterization, as long as she is nice.
So, she is indeed an attempt at Fall-from-Grace sans what actually made F-f-G a sympathetic, appealing character and probably one of the most interesting companions in PS:T. As in, the most shoehorned and unconvincing way to make a succubus redemption story instead of a background of defiance of one's pre-coded nature that follows the game's theme of a party with heavily messed-up pasts that everyone has to carry as a burden.
A personal take and all - but is there actually a single not poorly made / unappealing romance subplot in either Pathfinder game apart from Kalikke, a DLC character added some time after release of the first game? I know there are Tristian fangirls out there, but (again, personally) he's yet another case of "my character can stand him because he's nice and LG and all, but I, as a player, hate him so much, and end up pulling my roleplaying muscle being polite to the bugger". And as for WoTR, I've heard some... things about Camelia. I mean, to each their own and all, but there's such a thing as *too* edgy. Neither Minthara nor Lae'zel can hold a candle to her in that regard...
