as I mentioned before, about 20% of individuals in each population is superfluous. But why did they come into existence? Is it by chance? Not all all. This share of specimens has to fulfill its role - they should fall victims to predators, perish in natural calamities, be exterminated by their kin. Why? If those defective or second-best individuals are eliminated, the overall pool of genes in the population improves. The ones to survive are the fittest, the most flexible and adjustable plants/animals/humans. The natural selection is done in such a way that the most adaptable people survive, they give the best offspring, after all. The population prospers. On the other hand, the weaker, less fit are designed to be eliminated, to die. I must find some good points in my CTB. I may die but my death will be more than useful for the "fellows". I should be happy and see the logic in this process. I will die but the better people will live. My death will serve the superior purpose. However sad it is for me to acknowledge this status quo.
