What explains the attitude of the General in the matter of the enemy soldier? Was it human consideration, lack of national loyalty, dereliction of duty or simply self absorption?

Explanation

The General was totally governed by self absorption. He was a patient of Dr Sadao and did not trust anyone except him when it came to his health. He could not take the risk of living unprotected if the doctor was executed for treachery. He had personal assassins whom he promised to use for killing the injured soldier. But ironically, he forgot his promise to help the doctor. Humanity was not his cup of tea.
