I just realized something. Throughout the course of the movie, Ratchet doesn't kill…anything! Clank only kills one guy–Victor–and even though Ratchet defeats Nefarious, he doesn't technically kill him. Qwark, Cora, and Brax all have higher kill points than Ratchet and Clank.
"So we fix our eyes not on what is seen, but on what is unseen, since what is seen is temporary, but what is unseen is eternal."

. Even though he survived the ejection, he landed on a field of poisonous ivies, which could probably kill him! Oh, and the Zurkons? He didn't kill any of them? Well, guess Brax had the highest kill count. He killed a swarm of Zurkons on his own! And Neffie, well Ratchet probably killed his organic body, but Neffie survived as a robot, so… nah. But wait! Those warbots that invaded Aleero city! He threw them to the capital ship, so I guess he killed a lot of robots that day.
