Rākṣasas are understood to be accustomed to eating their own sons, as snakes and many other animals sometimes do. At the present moment in Kali-yuga, Rākṣasa fathers and mothers are killing their own children in the womb, and some are even eating the fetus with great relish. Thus the so-called civilization is gradually advancing by producing Rākṣasas.
Alas, my sister (Devaki)! Alas, my brother-in-law (Vasudeva)! I (Kamsa) am indeed so sinful that exactly like a man-eater (Raksasa) who eats his own child, I have killed so many sons born of you - SB 10.4.15
