Neutral good way: help the druids and kill the tieflings or drive them out of the grove, and then take the quest from Kagha to kill the goblin leaders. Get a party with druids and elves. Khalsin must survive. Everything is the same as now in the game in a good way, but at the party there are druids instead of tieflings. Kagha is alive and has come to terms with the fact that Khalsin is her leader. The opportunity to have sex with Halsin.
There's nothing Neutral Good about that. There is actually a path in-game that can be considered somewhat neutral good and that is investigating Kagha and convincing her to renounce the Shadow Druids, leading to her redemption.
A neutral good person acts purely out of a desire to do good, without any ulterior motives like you'd have with either lawful or chaotic alignments.
