Bhagavad-gita 2.2-3 Lord Krishna chastised Arjuna because of his weak behaviour

The Supreme Personality of Godhead, Lord Sri Krishna said – kutas tva kasmalam idam - My dear Arjuna, how have these impurities come upon you? They are not at all befitting a man who knows the value of life.

In the presence of the Supreme Personality of Godhead, Arjuna’s lamentation of his kinsmen is certainly unbecoming, and therefore Lord Krishna expressed His surprise at such non-Aryan like behaviour. An Aryan knows the value of life and follows varnasrama civilization based on spiritual realization. Arjuna was a ksatriya and was deviating from his prescribed duties by declining to fight. This act of cowardice is described as befitting the non-Aryans.

Lord Krishna did not approve of the so-called compassion or false magnanimity of Arjuna for his kinsmen. People do not know where compassion should be applied. Material compassion, lamentation and tears are all signs of ignorance of the real self. Compassion for the eternal soul is self-realization.

For example, compassion for the dress of the drowning man is senseless. Outward dress is compared to the gross material body. A man fallen in the ocean of nescience cannot be saved simply by rescuing his outward dress or the gross material body. One who does not know this and laments for the outward dress is called a sudra or one who laments unnecessarily. Such a person does not attain opulences but only infamy.

Lord Krishna further chastises Arjuna - klaibyam mä sma gamah pärtha - do not yield to this degrading impotence. Only a Friend can call His friend impotent. Arjuna was being guided by the Lord Himself to overcome his weakness and to reveal the knowledge of liberation from material bondage.
