Why has god designed the world in this way, by keeping hunting and killing of other living being as a part of this living system?

Swami Replied: These hunting cruel animals were the soft animals killed in the previous birth. The butchers in the previous birth have become the hunted soft animals. All this is routine divine administration setup by God. There is nothing in this world, which does not come under the rule of God and hence there is no need to question anything here as uncontrolled injustice.
