Kansa, consumed by his greed and fear, imprisons Vasudev and Devaki and kills their children, fearing that one of them may be the incarnation of Vishnu who will kill him. He is reminded of his previous birth as a demon killed by Vishnu and becomes even more determined to kill Krishna, who is set to be born in the same family. However, he is ultimately defeated by Krishna, who embodies the ultimate power of good over evil.
