I kinda liked the video, as usual, but he makes some weird assumptions here. He keeps using the "scarf and camo" to explain where certain scenes take place (like Eli fighting snake), yet, in the scene where Miller is rescued, he simply states that "snake must have removed the scarf" in order to support his theory.
Secondly he refers to BB being a monster, as Miller said in MG2. I always took that expression as a comment to BBs combat abilities (not to mention he had a cyborg body so was naturally stronger, faster and more experienced than Snake to boot), so yeah. He's a monster in the sense that if you try to fight head on with your fists, you gonna get smacked real hard.
Third, he makes the same assumption that Snake is shooting the kids in the cages, when he has no reason to, to me it seems a case of classic misdirection (the trailer is most likely cut to another scene and some people make the connection between both scenes as if they are continuous when they probably aren't at all). If I'm not mistaken Yong also aluded to the fact that BB was trying to kill Chico, by strangling him. That was pretty much deliberate decision to make us especulate that. He was, as seen, trying the opposite, save his and Chico's life cause he would alert the guards.
Fourth, he makes another case for BB being a monster in the fact that he killed 4 soldiers point blank, but managed to avoid the fact that they are acting like "zombies". He dispatched 3 of them and the fourth didn't even react, so he wasn't being himself. The reason for this is yet unknown, maybe Mantis has something to do with this, even though snake could have CQC'd them to hell and back, things are not so cut and dry.
And fifth, he further proceeds with BBs psyche analysis by attaching that massacre at the village to him. He's covered in blood, sure, but what makes us certain the he was the one who did it? And for what reason? He's covered in blood, and in the next scene he's on his knees, and seems to be in pain (that cliched pose screaming at the sky like he lost someone important and couldn't save them in time). If he was the killer of all those people, would he act like that?
There are many valid points in this video, but I don't exactly agree with everything he said. I think the truth, like always, will be somewhere in the middle. Kojima seems hell bent on making us think that BB is a total monster, but I just see a lot of misdirection.
May I eat crow when and if the time comes, but for now these trailers - although amazing- have done little in terms of making me see the "demon" he wants us to see. Practically every trailer in the MGS franchise was either touched up, changed cronologically or even straight up made up :
-mgs2 with snake fighting the harrier on the Bridge over the Hudson,
-the alusion of Time Paradoxes in mgs3 to make us think it had something to do with VR,
-snake even had a different voice in one of the trailers in PW if I'm not mistaken
-That face octocamo with young snake in MGS4 (we didn't know about face octocamo back then which made people assume that there were 2 snakes, or a huge ass time lapse in between Acts)
