YMMV / Star Wars: The Clone Wars S1E17 "Blue Shadow Virus"

• Complete Monster: Dr. Nuvo Vindi, also in "Mystery of a Thousand Moons", is the Mad Scientist who recreated the titular virus, a disease that kills all who contract it and which no lifeform is immune to, after it had been wiped from the galaxy. Vindi not only brought the virus back, he converted it to an airborne strain so it could spread more easily. Vindi's ultimate plan is to send a virus-laden bomb to each key Republic star system, creating a galaxy-wide plague that could kill entire planetary populations. When his operation is put at risk by the Republic, Vindi just decides to prematurely activate the bombs while they're still on world, with the intention of killing everyone on Naboo, himself included. Though hired by the Separatists to perform these actions, it's clear that Vindi takes great joy in his work, and sees unleashing the revived virus as passing judgement on the galaxy that once "murdered" it.
