FRANCIS POV:
Survival of the fittest. The world is controlled by the will of the strong. The prey can't cross its predator, the natural set boundaries. Those who try to cross their boundaries get crushed, but that doesn't necessarily mean its unfair. Everything is a predator as much as it is a prey. We are not exactly classified into the weak and the strong, rather we are in categories of strong with weakness being the undeniable difference. For instance; A lion is strong to a cheetah, a cheetah is strong to a gazel, a gazel is strong to grasses, grasses are strong to the ground. So also a cheetah can't overcome its weakness to challenge a lion neither can a gazel overcome its weakness to challenge a cheetah in that order. Stay in your zone of strength and you'd live a long purposeful life.
