Gale not NG?
He is absolutely disgusted after the goblins win and says that it is against kindness and compassion, then he proceed to leave unless you achieve a difficult roll.
I honestly think he is more good than neutral, at least in the context of BG3.
I also view him more as a good man, even when he strucks THAT deal with a certain entity - he feels angry and disgusted that it is his only option left apart from exploding. And this is DnD after all, to a great extent! Everyone can be swayed with a proper roll of the dice, even the personification of goodness.
