What I thought was interesting is that he went into an exaggerated position of attention before his "if I die, if I die, then drink my skin and eat my blood" in a rehearsed rhythm -- that was his cadence. Military basic training units typically have a motto or platoon cadence that, when called to attention, they snap to the position of attention and shout out the motto as one unit in one voice. The wardrobe to the left of the screen could be a wall locker, and this could be his quarters. Also the need to hang his jacket up was straight up discipline, he didn't want his quarters or jacket out of the established SOP any longer that was required for him to make the video using that space. Also he tucks his shirt into sweat pants. No one does that because they choose to.

Its absurd, but this looks like he is in a training program for youth. The content of the cadence is possibly more disturbing in that context, because they aren't his words, those are the words of the institution and its not something you would expect in a program that teaches goofy kids self-esteem. Its something else.

Cult indoctrinated child soldiers?
