I believe human beings are not violent by nature. Unlike lions and tigers, we are not naturally equipped to kill with sharp teeth and claws. From a Buddhist viewpoint, I believe that the basic nature of every sentient being is pure, that the deeper nature of mind is something pure. Human beings become violent because of negative thoughts which arise as a result of their environment and circumstances.
I wholeheartedly support an appeal to those countries who at present employ the death penalty to observe an unconditional moratorium. At the same time we should give more support to education and encourage a greater sense of universal responsibility. We need to explain the importance of the practice of love and compassion for our own survival and to try to minimize those conditions which foster murderous tendencies, such as the proliferation of weapons in our societies. These are things even private individuals can work towards.
