Evil characters do not need to pass the "arch of redemption" for "character development". Please, let's destroy this standard of erasing evil characters and their evil personalities. This is not a mandatory ritual for "character development".
This. I would prefer to get rid of this entirely, but if it must exist (which it probably will since people seem to be obsessed with it) then there also should be a way to turn other characters to evil.
Bit odd trend that Minthara is the third Drow female romance option so far, but I can't think of a single male drow party member, much less romance option in any games.
I have a sad feeling a game that had this would make it be a Drizzt clone or have some forced redemption crap for anything to progress.
