"Kamsa was born to King Ugrasena and Queen Padmavati. However, out of ambition and upon the advice of his personal confidantes, Banasura and Narakasura, Kamsa decided to overthrow his father and install himself as the King of Mathura. Therefore, upon the guidance of another advisor, Chanur, Kamsa decided to marry Asti and Prapti, the daughters of Jarasandha, King of Magadha.
After a heavenly voice prophesied that Devaki's eighth son will slay him, he imprisoned Devaki and her husband Vasudeva and killed all their children; however Just before the birth of the seventh child of Devaki and Vasudeva, Lord Vishnu ordered Goddess Mahamaya to transfer the womb of Devaki to that of Rohini, another wife of Vasudeva. Soon, Rohini gave birth to Devaki's seventh son, named Balarama. The eighth son, Krishna, an avatar of the god Vishnu, was transported to Gokul, where he was raised in the care of Nanda, the head of cowherds. Kamsa sent a host of demons to kill the child Krishna, all of whom Krishna killed. Finally, Krishna arrived in Mathura and slew his uncle Kamsa."
Okay...what does this have to do with Jesus and the massacre of the Innocents?
Matthew 2:16 - Wikipedia
The stories are barely alike, only containing general similarities (a prophecy, a child, a king in fear of overthrow). So what?
