The origin of Kansa

I often wondered how Lord Krishna got an uncle — Kansa — who was a demon. Recently I read the story in the newspaper. Ugrasen was the king of Mathura and Karni was his wife, the queen of Mathura. The queen was very beautiful. Once while they both were strolling in their royal garden, a demon flew by. When the demon saw the beautiful queen, he fell in love with her (it was lust, not love). With his magical powers he somehow distracted the king, transformed himself into the form of the king, and made love to the queen, perhaps there and then, and flew away. The queen must have thought: What has gotten into my husband — all of a sudden he has turned into a sex stud!.

Anyway, the sperm of a demon begot a baby demon that later on turned into the famous Kansa. I wonder why this birth didn’t set the king into frenzy. After all there must have been some tell-tale signs of the queen giving birth to a totally different looking baby. There should be a hell of a difference between a human baby and a demon baby. Demons are supposed to be scary, aren’t they? Even if all baby’s are cute and somewhat have the same baby sort of appearance, you can notice the difference between a cow’s baby and a dog’s baby. There is some part of the story that we don’t know here.
