Blitzo Buckzo

Prime example is Helluva Boss. The main antagonists are Stolas' abusive wife Stella and her manipulative, scheming brother Andrealphus.

Yet, despite this, they're actually way less vile and heinous than our main protagonists, the daily mass murdering I.M.P. and even Stella's abuse victim Stolas, who allows I.M.P to commit mass murders in the first place.

Meanwhile Stella and Andrealphus are just "kill the heroes" villains who failed to do so.

Got any other examples?

I feel like he isn't exactly dead, just got killed, but sent back to hell as a sinner, if i know exactly of being dead and sent to hell from the human realm in Hellaverse works.
