This can be interpreted in an interesting way. In other words, it is possible that in this world line, the snake's place was entrusted to the real “Big Boss” rather than the “Federal Student Body President”. In other words, the Boss failed for some reason and Venom took his place.
"Kept you waiting, huh? Sorry I've been gone so long. I heard about what you've been doing and... well, I don't blame you. I know what it's like, losing everything. Makes you want to punish the world for being so cruel. But this isn't the way, Yukino. If the only way to make our Outer Heaven is by making hell for others, I'd rather remain a demon. "We'll find a way to make a place for all soldiers, without the help of any corrupt officials - a place where those like us, those who live on the battlefield, will always belong. I won't let you be used by anyone, Yukino, nor any of the members of our squad. People like Kaya may think you're nothing more than dogs of war to be used and thrown away, but she doesn't know your true value. "You're unbreakable. No matter what they throw at you, you'll never stop shining. You are true Diamond Dogs."
