Despite proclaiming that he is a god, Saturn just proves that he is a human every time he appears on screen.

He is so insecure and he needs so bad to prove that he is superior to others, even someone who is a slave like Kuma. Which is contrasted by the other Gorosei who are pretty self-confident and don’t need to prove anything. He fits the theme of Human contradiction so well, which is the main theme of the arc.

Everything he does gets back at him. He experimented on Ginny but ended up making a mini Nika. He ordered the wiping of Kuma’s personality but Kuma was still able to protect Bonney with willpower alone. Finally he allowed Luffy to escape by refusing to destroy Emeth.

It is ironic. In Kuma’s flashback, he told him that he can’t understand why humans always try to do what they are told not to do, but he ends up dying because of disobeying orders and refusing to destroy Emeth. It was because of his human need to prove himself that he disobeyed orders just like the people he consider insects. It is poetic.

He is a horrible person but an amazing character.
