While his door may be "closed," I think Scott is still afraid. He fought like he did back in Season 2 against Derek. Honestly, I don't think he trusts himself to know when to stop.

You also have to remember that Ethan and Aiden were Alphas before, and taught by Deucalion. They have accepted who they are, and what they've done. Scott hasn't.
