We're just gonna have to disagree on that, Corvo. The way I see it: Lightning would even work with the gods she hates if it meant saving those she loves and cares about and protecting all of humanity. Yes, she's still aggressive, rebellious, etc. but she can also see the forest through the trees now, so to speak. Etro is absolutely abhorrent for what she did to Lightning, I do agree on that. Again, maybe my mind is just reaching to find coherency where there is none.
The part about Hope and the Fal'cie: There is quite literally nothing to excuse this. HE FUCKING USED THE MEMORY CHIPS FROM FAL'CIE EDEN! He didn't create them, he salvaged them from a Fal'cie who was at the center of Barthandelous' plan.
