There's a point worth considering here which is that even the lion who founds the school thinks that he's helping the gazelles, and many of his lion friends seem to think he's crazy. Even starting from supposed good intentions, the lessons taught in the school are fundamentally based on a lion-centric worldview. Even with a "top-tier" education, the gazelles aren't being prepared to question the fundamentals of their situation in life, which is why they are still being eaten.
