Yeah, Jasper overshadowed Peridot because she was much more cruel to GASP specifically, but Peridot was the one who was so fixated on reactivating the Kindergarten, which would destroy all life on Earth. And Peridot seems to have experience operating Kindergartens, so she's likely got a pretty high body-count from other worlds.
