Now Larian did tweet this yesterday through the official BG3 twitter account in relation to Orin: "No, you can’t fix her. But… do try! What could go wrong? 🙂"
This gives me hope that Larian may also do this with the EVIL origins (emphasis very intentional). I would give Larian so much credit if they provided a "redemption" path for the evil companions Lae'zel, Astarion, and SH, especially SH, only to have them turn around and stab the PC in the back towards the end of the game. Now *this* would be good writing!
