SB 5.14.14
yada tu para-badhayandha atmane nopanamati tada hi pitr-putra-barhismatah pitr-putran va sa khalu bhaksayati.
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
In this material world, when the conditioned soul cannot arrange for his own maintenance, despite exploiting others, he tries to exploit his own father or son, taking away that relative’s possessions, although they may be very insignificant. If he cannot acquire things from his father, son or other relatives, he is prepared to give them all kinds of trouble.
Purport by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
Once we actually saw a distressed man steal ornaments from his daughter just to maintain himself. As the English proverb goes, necessity knows no law. When a conditioned soul needs something, he forgets his relationship with his relatives and exploits his own father or son. We also receive information from Srimad-Bhagavatam that in this Age of Kali the time is quickly approaching when a relative will kill another relative for a small farthing. Without Krsna consciousness, people will deteriorate further and further into a hellish condition wherein they will perform abominable acts.
