Three Things Kamsa Should Have Realized After Learning Of His Previous Birth

“Kamsa was made aware of his previous birth by the grace of Narada. He learned that in his previous birth he was a demon of the name Kalanemi and that he was killed by Vishnu. Having taken his birth in the Bhoja family, he decided to become the deadly enemy of the Yadu dynasty; Krishna was going to take birth in that family, and Kamsa was very much afraid that he would be killed by Krishna, just as he was killed in his last birth.” (Krishna, The Supreme Personality of Godhead, Vol 1, Ch 1)
