If Heaven exists- which person's presence would make you immediately run out?

Let’s assume heaven exists. You arrive at the gates and it’s gorgeous; it’s everything you ever hoped it would be.

BUT… when you pass through the gates, you see “name that person” standing there, and without a second thought, you run out screaming.

Who would make you instantly turn away from Heaven?

I think I’d run out if I saw Hitler there. Or maybe Gilbert Gottfried… could you imagine that voice for eternity? AAAAHHHH!
