>>2470395Satsuki admitted she's been exactly like her mother because of what she's done, but her goals weren't only for her own selfish needs, she wanted to save the world. She was prepared to die trying to achieve her goal, and didn't care if others hated her for it as long as it was done.

She wasn't obsessed with her tyranny, she was obsessed with the image of victory. She thought the only way to achieve her goals was to do what Ragyo does and defeat her in her own game.
