Huh. That’s a really interesting point. I can see some differences – Mordo has a bit more psychological independence than the Operative, so that when the crisis of faith hits one can’t go on and the other rebels. But also I would argue that Mordo doesn’t approach the Operative’s fanaticism until toward the end of the movie; he’s more easy-going in the beginning before the pressure gets increased and he starts retreating back to first principles as a defensive measure.
But yes, I’m sure Chiwatel Ejiofor built off the Operative in building his character.
