The survival of a species

I was watching Animal Planet on TV and I saw this episode about lions and their behaviour.

I felt a empty sadness when they said that the lion will kill off all the off springs/cubs of the another lion if their "father" loses in the battle for pride. Why? , why must such innocent creatures be killed because their "parent" did not keep up the deal to survive or loss in the battle. Now nature says it's because nature wants the best for that species to survive. Well, isn't it's father was once a champion then when it took over the pride of the colony?



When you see this little creatures, you pity them, for no reason they are not to live their lives but be killed because they were born at the wrong time and at the wrong place.

Where is the merciful god in this scenario?

You will not be able to see or reason it without moving or climbing up a higher level to understand this but that's the way it should be in order survival that species can be attained.

YOU must look at it from a ONE entity formula in order to understand nature's plan. An older weaker lion will lose to a younger and stronger lion, that's quite clear in this case the older lion weakens as it aged. Nature needs to get rid of the weaker ones so that their life line will continue, the younger lions must take charge and have their own cubs and the only way is to kill off the cubs of the older lion in order that the females will go into estrus and mates with the new dominate male.
For lions as a whole to survive, those cubs has to be sacrificed to make way for the new dominant and strong ones to carry on the new life line of LIONS.

That's the reason behind such horrors of nature as you see it at a lower level of understanding of life on an individual scale. But if you look at it from a bigger scale of species you will realize that there is a system in action laid down, a blue print of infinity that drives the world.
