If I were to rate it, I would see it as pragmatic solution - neutral? You are willing to help, but not endanger yourself more the necessary for the sake of others. It is a path that leads to a lot of bloodshed that could be avoided, if one would just remove just the leaders and perhaps their immediate guards. And even if you deep goblins as evil that needs to be remove, going it with Helsin doesn’t put civilians in danger.
Hindsight decisions though. Its much less clear what to do on someone's first playthrough.
