This is a great portrayal of Doom. Not just the ending, where he saves his country and destroys Richards, but also how what he's completely willing to sacrifice a few thousand of his countryfolk just to win...and has a change of heart. To me, this is the Doom that can both kidnap a child to hell and deliver the child of his worst enemy, this is a Doom that is complex and might not always know his own mind or make the right decisions...but never doubts them, not even for a second.
