You missed the part where Lucifer seems like an unbeatable boss and everybody accepts it as truth. Then, 6 years later some datamining led to a secret item that unlocks a third ending in which you overpower and absorb Lucifer’s soul. You wake up in the basilica, shunned and attacked by everyone there, and when you run out of health, you get back up in a cutscene as Lucifer-reincarnate and destroy both the heavens and the hells.
This secret ending becomes wildly popular and is seen as the most interesting ending in the game. However, it’s also never referenced again in the franchise.
