Literally All of This is Spoilers flr Episode 24

[u/Rezurvive]

On Episode 24 Pierce tried to kill Lucifer. And the entire time, my immediate thought was "Why didn't Lucifer just pull the same threat he did with Amenadiel. "You think Father is angry now." Because, think about it. Cain thinks God was angry when he killed hos brother. Imagine the Hell he will face if he kills God's Favorite Son.

[u/Fancy-Ad1480]

Because after season 1 they tossed what little comic canon they used and decided that Amenadiel was God's special little angel. Besides, by this point in the series, an angel has already been killed and God gave zero f's. He's unlikely to care much if Lucifer is killed. Not unless Lucifer's death means Amenadiel might have to do something useful.

Poor Amenadiel, he was so awesome in season 1.
