Everything you see exists together, in a delicate balance. As king, you need to understand that balance, and respect all the creatures-- from the crawling ant to the leaping antelope.
But, Dad, don't we eat the antelope?
Yes, Simba, but let me explain. When we die, our bodies become the grass. And the antelope eat the grass. And so we are all connected in the great Circle of Life.However, the Antelope were less sanguine about the "Circle of Life" philosophy promulgated by the ruling monarchy. They believed it to be propaganda intended to the keep the Antelope in their place as a food source, and justifying their savage murder and consumption — sometimes while still living — whereas the Lions lived without a care and died peacefully at a ripe old age as the direct beneficiaries of their speciest idealogy.
Thus the antelope resolved that the Lions might just as well skip the eating the Antelope part and get to the bodies becoming grass part of the Circle of Life a bit quicker. Unbeknownst to King Mufasa, they were busy developing opposable thumbs and large caliber weaponry.
The "Circle of life" was about to become a semi-circle for some.
