But only if they aren't acting as Devan's stunt double.

The problem isn't that Devan is doing it, the problem is theres little reason for Devan to do it other than "Lol he's evil, just stoop him, mahnz". If you take the same story and then toss in say, Eggman, in place of Devan that doesn't make the story any better. Heck, Eggman has less motivation than Devan and would ultimately make the story worse.

However, if you're going to take the time to make a good motivation for Eggman, you could have also took the time to make a good motivation for Devan and made the pack that would kick this extremely dumb stereotype to the curb.
