ur not supposed to get the "good" ending where everyone is happy and theres no war and no magic or fun. why would you want a whiteknight kingdom. did you really play this whole game through being a saint? if not, why you trying to be one at the end? you are supposed to pick to become the divine, get the OK ending, and get the foreshadowing of a future sequel possibility of you as a divine working with Malady, etc. to do her favor with the whole Demon situation. if you didnt notice, demons throughout the game are sorta not talked about and by far stronger than everything else/key to the plot, but theres no ending that really touches on them except the one where the demon army is used to crush the eternals/sworn. pick divine, be greedy, get the ending where everyone on your boat is happy. thats the "good ending"
