I love the comment from Cavill's August Walker.
"How many times has Hunt's government betrayed him, disavowed him, cast him aside? How long before a man like that has had enough?" - Walker
Well, for a little over two years we have been spotting serious blowback in IMF operations, we have a penetration. The other day, we decoded a message on the Internet from a Czech we know as Max. - Kitteridge
Its like ever since Phelps went rogue in the first movie the series has been explaining that maybe he was doing what he thought was right just as Ethan and Soloman were doing. Walker is dressed similar to how Kitteridge was with the iconic CIA agent duster. I don't know if that is intentional. However throughout the last few films every character has spent time as a disavowed or rogue agent.
The secretary even orders Ethan to act against the governments orders in Ghost Protocol.
Now, I've been ordered to take you back to Washington, where the DOD will label you as a rogue extremist and hang the Kremlin bombing on you and your team. Unless, you were to escape somewhere between here and the airport, having assaulted Mr. Brandt and me. - Secretary
Rogue Nation is really a story about the how wars take place in the opaque, the shadows. They need a lack of over sight to exist for the impossible mission to be accomplished, however if it isn't the agents are thrown under the bus by their government.
They don't care if you live or die. Lane, Atlee, Your Government, my Government, we only thing we are doing the right thing because that's what we choose to believe. - Faust
That's something of a reality I've seen through my own personal work. There are times in Rogue nation when it is hard to differentiate between the Rogue IMF Ethan controls and the Rogue Nation that Lane controls. Who would have made a better world? Obviously we as the audience root for Ethan, but is he always right, do is actions still have dangerous consequences?
I helped my government kill many innocent people and more. So much more. Killing to keep things as they were. And now I'm killing to bring about change. - Lane
I wonder if at the end of the film Walker will not be able to pinned down to a single Hero or villian, protagonist or antagonist role, he might be a much more complicated character, as Hunt, Faust and Phelps all were.
Hunt is uniquely trained and highly motivated - a specialist without equal - immune to any countermeasures. There is no secret he cannot extract, no security he cannot breach, no person he cannot become. He has most likely anticipated this very conversation and is waiting to strike in whatever direction we move. Sir, Hunt is the living manifestation of destiny - and he has made you his mission.
