10 Most Brutal Murders The Joker Has Ever Committed

10. "Merry Christmas"

Towards the end of the No Man's Land arc back in 1999, the Joker was feeling extra festive, and decided to give Batman an early gift. However, it's not exactly in his nature to give something without a catch.

Now, a scavenger hunt could be a fun gift when given the right amount of thought, but this was anything but fun. Joker had kidnapped and hidden a bunch of babies. Not only that, but he had each possible location rigged with traps and explosives.

As news of his location gets to the team, only Sarah Essen is at the correct place. She figures there is no time to wait for backup and heads down to the basement to confront Joker alone.

She finds him holding a baby, while surrounded by countless other children. In order to escape the scene, Joker throws the baby in the air and causes Sarah to drop her gun as she tries to catch the child. Joker points his gun at Sarah and wishes her a merry Christmas before pulling the trigger.

Even the Clown Prince realises he has gone too far. As he gives himself up to the police, his face appears to show a rare feeling of pure regret.
