To say that a sentient being is not harmed by death denies that the being has the very interest that sentience serves to perpetuate. It would be analogous to saying that a being with eyes does not have an interest in continuing to see or is not harmed by being made blind. The Jains of India expressed it well long ago: “All beings are fond of life, like pleasure, hate pain, shun destruction, like life, long to live. To all life is dear.
