doomsday engine needs a new doomsday fuel pressure regulator

September 11th, 2015: Are there any super villains who want to kill ALL life, not just the parts that look like them? I know Batman's frienemy Ra's al Ghul wants to destroy HUMANS but leave like, all the dogs and cats still running around. If he sold his plan not as "EVERYBODY DIES" but as "WELCOME... TO PLANET PUPPY" he honestly might get more support for it??
