Because word placement can change different meanings in a sentence.
Team Skull was the result of limited resources (trial captains being treated as one, since Guzma wanted to become a trial captain himself), and Team Skull would've never existed if Lysandre executed his plan.
Of course I see the problem, as did Lysandre, because that would involve killing animals in the progress. Lysandre loved Pokemon, but he knew he had to kill them all if he wanted to wipe out humanity to end greed, war, and suffering, just like what's happening in the real world today, which was why he shed a tear. There's 7 billion of us, and our resources can't feed them all, while other animals are suffering to extinction because of our overpopulation. That is why he's the true hero of Pokemon XY, and you, the player, were the true villain.
