I think its funny how this anime is called Kill la Kill, but our protagonists never actually kill anybody. Ryuko and Satsuki don’t have any blood on their hands, but not from a lack of trying.
Ryuko and Satsuki both want to kill someone more than anything in the world. Ryuko wants to kill Nui for murdering her father, and Satsuki wants to kill Ragyo for killing her father and baby sister (and I’m pretty sure for molesting her for all those years). However, both Ryuko and Satsuki fail at killing their nemesis.

Ryuko goes of the deep end in episode 20, and goes straight for Ragyo and Nui. Ryuko has a fight with Nui and stabs her through the chest. Nui pretends to dramatically die, and Ryuko has a devilish smile on her face. She takes satisfaction in watching her “die”. But then Nui’s all like,“Just kidding”, and Ryuko gets pissed, then gets brainwashed by Junketsu.

Satsuki has a simular situation. She stabs Ragyo in the back and gives a speech she had been preparing her whole life. She chops her head off and has a serious, but satisfied face and only says,“It is done”. But of course, Ragyo can’t be killed so easily. Then Satsuki loses in a fist fight with her, loses Junketsu, and blows up the stadium, and then gets captured.

Then in episode 24, both Ryuko and Satuki slice up Ragyo with the scissor blades. And we all know why that failed. That little armless psychopath decapitates herself.

Despite their burning hate for their enemies, they cannot kill them. At one point, Ryuko even has the chance to kill both Nui and Ragyo. Instead of chopping Nui’s arms off, she could’ve chopped her head off. And when Ragyo fails and is just floating in space, she could’ve charged at her and taken her out, but she actually asks Ragyo to come back to Earth with her. She says,“Yeah Mom. The Earth ain’t gonna turn into a cocoon sphere, and you’re coming back with me”. She forgives her and calls her Mom, which she had refused to do so earlier.
Ryuko rises above that hate and becomes a better person than both Nui and Ragyo.

Those two are so rotten that they wind up taking their own lives. Nui sacrifices herself without question and Ragyo can’t handle her own failure and she rips her heart out then crushes it. Her humanity so so far gone that she couldn’t even bother to stick around to be a good mom to Satsuki and Ryuko. And Nui was never human to begin with. Just a bundle of pure evil.
In the end, they were the only ones with blood on their hands.
