In the fight against Hachi and Soi-Fong after being mortally wounded, Barragan the way he called them ants throughout the fight why didn't he want to take out Hachi or Soi-Fong my reasoning being he should have wanted to take out the people who costed him his life but instead suddenly turned against Aizen all of a sudden? Why did he do that?
He decided to take on the one who cost his pride than his life. He was initially the God-King of Heuco mundo and the arrogant overlord of all hollows until Aizen with Gin and Tousen made his entry and dethroned him from Las Noches with a display of his Shikai. Barragan had merely been reduced to being a henchman of a renegade shinigami from that of a king of hollows which hurt him deeply and towards his last breath decided to take out Aizen who had brought him this dishonor.
1Yes, more than that, he lost his throne to a shinigami. As a hollow it should be even worse.– RikkinSep 10, 2013 at 20:28
