Answer -
Though all human beings come from the same stock, yet by the passage of time they are divided into the narrow walls of nation, religion, caste and creed. When organised wars started, more and more deadly weapons were used and the feeling of animosity grew stranger.
Gradually hatred with the enemy country became an accepted feeling and it was considered to be justifiable. This feeling of justifying the hatred grew stronger during wartime. Now hatred against a member of the enemy race is considered totally justifiably, more so during war time. That is why the prisoners of war are treated in such an inhuman way.
But still we find a few exceptional human beings who rise above these narrow prejudices. Survival of humanity and of human beings is of paramount importance to them. Still we can find a large number of people in the whole world those not only want to safeguard human values but they are against wars also.
They feel that possession of deadly atomic weapons can totally destroy the world. That is why Dr. Sadao despite being deadly against the prisoner of war, who belonged to an enemy country, treats him and saves his life. His medical profession had trained him to save the life of a human being, as far as he could do so. This bond of humanity makes a human being rise above the narrow prejudices.
