Keiko preferred the company of people to other killer whales. He preferred a handout to catching his own food.Isn't the Welfare program the same thing? People who have spent their entire lives on the government dole have lost the ability to hunt. They have also lost their freedom, for in accepting the handout, you become dependent on the handout giver, as captive as any killer whale.
Is it any wonder that people, like animals in captivity, occasionally lash out and kill?
