Herein, why did the Hogyoku reject Aizen?

User Info: SaydeWindsaur. Wrong, the Hogyoku did reject Aizen (out of Aizen subconsciously wanting to be weak), hence why he returned to being a Soul Reaper (or possibly weaker, since he apparently lost his Zanpakuto).

Similarly, is Aizen a villain? Sōsuke Aizen is the overall secondary antagonist of the anime/manga series Bleach, serving as the original main antagonist of the majority of the series. Aizen served the Gotei 13 as the captain of the 5th Division, until he revealed himself to be a traitor and abandoned the Soul Society.

Keeping this in consideration, why did Aizen want to kill the soul king?

He threw away his Captain position, essentially a death sentence since the other 10 captains are now actively trying to kill him. All he wants, is revolution. His intellect is a blessing and a curse; he sees only the imperfections of their world, and he wants to change it all, by any means necessary.

What happened Sosuke Aizen?

Sōsuke Aizen in "end of hypnosis" No one stands on the top of the world. After waging war against Soul Society with an army of Arrancar, Aizen was defeated by Ichigo Kurosaki and sealed away by Kisuke Urahara, and then imprisoned for his crimes.
