User blog comment:NerdWithAKeyboard/Pure Evil Villains Who Never Killed Anyone/@comment-36575156-20180915202232

How about Unalaq from Legend of Korra? He is Pure Evil; a pure sociopath with a god complex and arguably the most despicable villain in this series. However despite his iredeemable nature, Unalaq himself didn't kill anyone. He threatened to kill Jinora and attempted to murder his niece, Avatar Korra but didn't do so due to interference. Even when fusing with Vaatu and becoming the Dark Avatar, Unalaq caused mass destruction but no one was implied nor even confirmed to have died from his attack. And finally Unalaq himself was defeated without having taken a life.
