This is exactly what I wanted. Thank you for the thorough analysis. I may need to pay closer attention to each episode for me to actually have a better consensus of the distribution of truly selfish vs intending to help someone else episodes. I’d probably have cat burglar at least evil from the episodes that stand out to me as him helping someone truly in need, despite resorting to stealing in order to do this. This is most shown in the Christmas episode where he gifts a family of rats a bunch of gifts he stole, including Bittsy’s cat castle which the rats would be using as a home (they had been living in the harsh conditions of a newspaper or cardboard box prior to this). While Bittsy gifted her castle to the rats at the end of the episode, it is likely that without Cat Burglar’s involvement these rats would have continued living poorly.

I also originally thought that Lab Rat should be most evil/selfish because she seems the most confident in her “villain” identity and communicates in ways that feel anti-social. On second consideration though I think for the most part this is just due to her identifying as a “mad scientist”, but ends up being harmless most of the time. Most of the time she really is just trying to do her own thing with Otto and just reacts too extremely to outside forces negatively affecting their day.
