Well, unless it was Eobard who annoyed Barry throughout 2020-2024.

By the way, in the comics Eobard knew that he could not kill the Flash without losing his Speed Force, but thought that traumatizing Barry was a fair deal. He still needed him to become the Flash, but he just wanted to be a dick to Barry, so that later he could scream "IT WAS ME, BARRY!" at him.
