Like Agent Ward! He got to kill people as a Shield agent and Hydra agent, and then got to kill even more people after he was with neither organization!

This guy looks just like Ward. Maybe it's him, I dunno. But if they are looking for teachers, maybe they should use a different actor, cuz, well, he's kind of a bad-guy :) Unless you want your kids being trained by Hydra... which they already are, in a way.
HAIL HYDRA!
