Lysandre's line "So start up the battle I'm ending the game!" has another meaning as it was his plan to kill most of the planet's human population as well as all of the pokemon. Thus if he would've won the battle then there would be no more pokemon games as all pokemon would've been eradicated. When I heard that line I was like "FIRE!!!!!"
Rose is pretty much the Thanos of the Pokemon universe. He's got a noble goal but to him the ends justify the means so whats a little dirt on the hands if you get the garden blooming?
