So we're just about stumbling into atrocities and healing and keeping Arabella alive because if something happens to her then this has all been for absolutely nothing.

It's not been without pitfalls and consequences. There are lines that can't be crossed. Kagha was tripping and we don't stand for poisoning children (as a rule), so she died and her followers committed mass slaughter. Ended horribly. Arabella is good though.
