Surely the mass of humanity is more "awful" now than it was before "The Great Flood"

My question was serious. Obviously there was killing long ago, but it was work in brutish times, in pursuit of straightforward political and economic goals. It wasn’t “evil” like Vlad the Impaler, or Charles Manson.

So who IS the earliest recorded “evil” human? Fictional characters are allowed, but I’m not sure Cain the First Murderer qualifies as truly “evil.”
