The Supreme Living Being is perfect in all relations with His pure devotee. Śrī Arjuna is one of the typical pure devotees of the Lord reciprocating in the fraternal relationship, and the Lord's dealings with Arjuna are displays of friendship of the highest perfect order. He was not only a well-wisher of Arjuna but actually a benefactor, and to make it still more perfect the Lord tied him into a family relationship by arranging Subhadrā's marriage with him. And above all, the Lord agreed to become a chariot driver of Arjuna in order to protect His friend from warfare risks, and the Lord became actually happy when He established the Pāṇḍavas to rule over the world. Arjuna remembered all these one after another, and thus he became overwhelmed with such thoughts.
(Srimad Bhagavatam-----1:15:4-----purport).

Jarāsandha was a very powerful king of Magadha, and the history of his birth and activities is also very interesting. His father, King Bṛhadratha, was also a very prosperous and powerful king of Magadha, but he had no son, although he married two daughters of the King of Kāśī. Being disappointed in not getting a son from either of the two queens, the King, along with his wives, left home to live in the forest for austerities, but in the forest he was blessed by one great ṛṣi to have a son, and he gave him one mango to be eaten by the queens. The queens did so and were very soon pregnant. The King was very happy to see the queens bearing children, but when the ripe time approached, the queens delivered one child in two parts, one from each of the queens' wombs.

Karṇa: Born of Kuntī by the sun-god prior to her marriage with Mahārāja Pāṇḍu, Karṇa took his birth with bangles and earrings, extraordinary signs for an undaunted hero. In the beginning his name was Vasusena, but when he grew up he presented his natural bangles and earrings to Indradeva, and thenceforward he became known as Vaikartana. After his birth from the maiden Kuntī, he was thrown in the Ganges. Later he was picked up by Adhiratha, and he and his wife Rādhā brought him up as their own offspring. Karṇa was very charitable, especially toward the brāhmaṇas. There was nothing he could not spare for a brāhmaṇa. In the same charitable spirit he gave in charity his natural bangles and earrings to Indradeva, who, being very much satisfied with him, gave him in return a great weapon called Śakti.

Jayadratha: Another son of Mahārāja Vṛddhakṣetra. He was the King of Sindhudeśa (modern Sindh Pakistan). His wife's name was Duḥśalā. He was also present in the svayaṁvara ceremony of Draupadī, and he desired very strongly to have her hand, but he failed in the competition. But since then he always sought the opportunity to get in touch with Draupadī. When he was going to marry in the Śalyadeśa, on the way to Kāmyavana he happened to see Draupadī again and was too much attracted to her. The Pāṇḍavas and Draupadī were then in exile, after losing their empire in gambling, and Jayadratha thought it wise to send news to Draupadī in an illicit manner through Koṭiśaṣya, one of his associates. Draupadī at once refused vehemently the proposal of Jayadratha, but being so much attracted by the beauty of Draupadī, he tried again and again. Every time he was refused by Draupadī.

King Parīkṣit married the daughter of King Uttara and begot four sons, headed by Mahārāja Janamejaya.
Mahārāja Uttara was the son of Virāṭa and maternal uncle of Mahārāja Parīkṣit. Irāvatī, being the daughter of Mahārāja Uttara, was the cousin-sister of Mahārāja Parīkṣit, but cousin-brothers and -sisters were allowed to get married if they did not belong to the same gotra, or family. In the Vedic system of marriage, the importance of the gotra, or family, was stressed. Arjuna also married Subhadrā, although she was his maternal cousin-sister.
(Srimad Bhagavatam-----1:16:2-----translation and purport).

In the age of Kali, the women and the children, along with brāhmaṇas and cows, will be grossly neglected and left unprotected. In this age illicit connection with women will render many women and children uncared for. Circumstantially, the women will try to become independent of the protection of men, and marriage will be performed as a matter of formal agreement between man and woman. In most cases, the children will not be taken care of properly. The brāhmaṇas are traditionally intelligent men, and thus they will be able to pick up modern education to the topmost rank, but as far as moral and religious principles are concerned, they shall be the most fallen. Education and bad character go ill together, but such things will run parallel. The administrative heads as a class will condemn the tenets of Vedic wisdom and will prefer to conduct a so-called secular state, and the so-called educated brāhmaṇas will be purchased by such unscrupulous administrators.
(Srimad Bhagavatam-----1:16:21-----purport).

This sort of behavior for a kṣatriya is praiseworthy in the sense that a kṣatriya must show his power of chivalry to his would-be wife so that the daughter of a kṣatriya can see the valor of her would-be husband. Even the Personality of Godhead Śrī Rāma displayed such a spirit of chivalry during His marriage. He broke the strongest bow, called Haradhanur, and achieved the hand of Sītādevī, the mother of all opulence. The kṣatriya spirit is displayed during marriage festivals, and there is nothing wrong in such fighting. Lord Śrī Kṛṣṇa discharged such responsibility fully because although He had more than sixteen thousand wives, in each and every case He fought like a chivalrous kṣatriya and thus secured a wife. To fight sixteen thousand times to secure sixteen thousand wives is certainly possible only for the Supreme Personality of Godhead. Similarly, He displayed full responsibility in every action of His different transcendental pastimes.

Śrīla Jīva Gosvāmī directs that drinking against the principles of scriptures, such as the sautrāmaṇī-yajña, association with women outside marriage, and killing animals against the injunctions of scriptures are irreligious. In the Vedas two different types of injunctions are there for the pravṛttas, or those who are engaged in material enjoyment, and for the nivṛttas, or those who are liberated from material bondage. The Vedic injunction for the pravṛttas is to gradually regulate their activities towards the path of liberation. Therefore, for those who are in the lowest stage of ignorance and who indulge in wine, women and flesh, drinking by performing sautrāmaṇī-yajña, association of women by marriage and flesh-eating by sacrifices are sometimes recommended. Such recommendations in the Vedic literature are meant for a particular class of men, and not for all. But because they are injunctions of the Vedas for particular types of persons, such activities by the pravṛttas are not considered adharma.
(Srimad Bhagavatam-----1:17:38-----purport).

There must be compulsory marriage of young boys and girls attaining twenty-four years of age and sixteen years of age respectively. There is no harm in coeducation in the schools and colleges, provided the boys and girls are duly married, and in case there is any intimate connection between a male and female student, they should bemarried properly without illicit relation. The divorce act is encouraging prostitution, and this should be abolished.

Utathya: One of the three sons of Maharṣi Aṅgirā. He was the spiritual master of Mahārāja Mandhātā. He married Bhadrā, the daughter of Soma (moon). Varuṇa kidnapped his wife Bhadrā, and to retaliate the offense of the god of water, he drank all the water of the world.
