Papa Vellek's hallucinatory resurrection.
He is a psycho and his mission is to cure his ailment with a good splash of pacifism. The world needs this cure according to him, but he cannot see what it does if all of us were sheep. Aggression has been part of humanity since we found sticks and stones been good things to wage war.
Our culture has very long roots that goes deep into the aggression. The universe itself is a very violent place. There is no peace. Instead extremly chaotic events that violently churns the cosmos. So it's right that they described this pacifistic bioweapon as lunacy. And I'm extra pleased Fletcher did what any good man should do despite the risk. I don't know how he thought he was going to get away with it?
The plan was suicidal. And almost equally the same with the plan on sending the biggest fighters in the camp full of sheep. I snickered a bit when the guards turned out be the pure animals. A human guard would understand their subjects and not try to entice the biggest person in the room to kick his teeth in. So it was a nice move on shoving that platter on his face and see if he eats it.
What I don't understand is why they let the Master Chief in the field mission. The man visibly weak and he was in no position to go out with the guys. The special ops can do all things he can and the old man can stay behind the bulk heads and be safe. But no, out he goes with the boars.
