But that's exactly my issue. Why do all "good" companions have to be characters who have questionable morals and judgment at a minimum, and it is my job as the PC to fix them and help them redeem themselves and thus become "good"? I am utterly tired of that trope. I just want companions who are undeniably good and don't require any redeeming or fixing on my part.
I agree that trope is overplayed, but I don't think it's in play here specifically. Larian has said that these aren't the good companions, and that they'll be introduced later. So while they may still do what you suggest, my view of what we have now is that these are companions that aren't explicitly good but have the potential to be good.
