The Boys: 10 WTF Moments

Bill Butcher puts the "anti" in "anti-hero".

While we can all fall for his quick wit, can empathise with his past trauma, and agree that superheroes need to be kept in check, sometimes Billy's vengeance doesn't just step over the line, but it stops to stamp on the line's head.

After The Boys use Mesmer, a supe with the ability to read people's minds and histories by touching them, Mesmer gives Homelander pictures of The Boys captured on Mesmer's home security camera.

Understandably angered by Mesmer's betrayal, Butcher tracks down the cowardly former child star and makes him pay for his betrayal.

While momentarily seeming like Mesmer may have something more to offer Billy, the thought of him making it out alive is soon crushed as Butcher repeatedly slams Mesmer's skull in to the bathroom sink.

This is an unflinching, graphic death that shows that in this world not only are heroes not heroes, but the people fighting the heroes are also pretty deplorable.
