No, that's not what I'm saying. Yes, they had diseases and they had to be put down. I got that. But ultimately, I felt the sequence showed that they were just as wrapped up in the greater machinations of what it meant to be a part of Big Boss' army.
"We live and die for you, Boss."
The part where you mow down the soldiers in the room, with the Peace Walker theme playing on the cassette tape, was very effective in showing the distorted nature of what Diamond Dogs and ultimately Outer Heaven is all about. Even though Huey was a dick for most of the game, he speaking some truth during this scene. The soldiers in DD and MSF were truly just pawns. Even though those soldiers died in truly horrific ways, Diamond Dogs were out getting new ones not long after. I kinda felt guilty for essentially kidnapping soldiers and brainwashing them into joining this massive, nuclear armed cult.
Again, I realize they were all infected and they had to be put down, but it still was effective in showing the complex that Big Boss and the others created, and the one the soldiers ultimately bought into.
