>>41873651There are two explanations that make sense to me:
1. Rose is batshit fucking retarded and convinced himself it's a good idea to throw away everything he's built up for his whole life and is having a tantrum over Leon not doing the same.
2. He's secretly got a master plan that is never once mentioned at any point, and this would be ruined if (you) became the new champion, which he foresees with his vast intellect which served him so well thus far as evidenced by his owning essentially an entire region by himself.
