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?

Used to not care

That I'll never pass for kind person

Or a perfect daughter

I did not

Want to play this cliche part

But deep inside

I knew if I finally see the light

I would break my bad side's heart

Who is that girl I see

Staring straight

Back at me?

Why is my reflection someone I don't know?

Why do I wish to try hide

a part of me

Though I've tried

What if my reflection showed

The light of me inside?

What if my reflection showed

Who I am inside?
