It seems to me they adapted whatever the original outline was for his interactions with the Gur into a softer, more palatable version for full release.
Basically, I imagine originally he had to confront something bad he did to the Gur in the past of his own volition: Now it's changed so the (seemingly one and only) issue he has with the Gur right now is something he did under Cazador's control, so he isn't even truly responsible for it, but he can still make an effort to try to fix it.
I find it peculiar that, when he remains a Spawn but you kill the 7k victims, he tells Ulma "I've inflicted enough pain on your people". Was this acknowledgement of his past deeds, perhaps? It's the closest thing we have. I guess I'll have to fill in the gaps, there.
