I also got this bug at the same location. Leaving the area and trying to long rest somewhere else doesn't help either. It's definitely a bug and I haven't found a fix for it. I tried just knocking him out, which then leads to the other inactive party member attacking us as well(unless they got a hit in to Gale - which usually resulted in his death since my other inactive member is Laezel), and knocking out doesn't seem to work as it still just kills them and you can't help them back up since it's considered an enemy. If Scratch is around, he will turn hostile as soon as one of the non-active party members is attacked. It's a very frustrating bug.
I read that this used to be an issue in the Blighted Village, looks like the problem has moved now to the Zhentarim hideout. I've tried all the fixes I saw for this issue and none of them work. Ie: going somewhere else, incapacitating strikes, etc. I'd rather not have to kill everyone but who was in my party at the time lol. I will also mention - Gale loves me in this run-through so I highly doubt this is a feature.
Edit: So, I just tried continuing without taking a long rest just to see what else I could do. Literally every single NPC in the entire world is now hostile towards me and attacks me on sight. Essentially every NPC that isn't in my party turns red when I approach. So, idk what killing the Zhentarum Gang that attacked me first did, but apparently the entire world knows and hates me for it.
