As pointed out by Srila Prabhupada in his purports to Chapter Two, Texts 5 and 8, of this canto, Marici's sons were condemned for their offense against Lord Brahma, and in addition Hiranyakasipu once cursed them to be killed by their own father in a future life. This curse was fulfilled by Vasudeva's letting Kamsa murder them one by one.
