Can you name that Supergirl story?

Jim asks,

I’m looking for a Supergirl story from the early seventies about a scientist who tried to destroy the world because it was so damned evil. Kara thwarts his plan but in the end she is philosophical; musing about his satellite’s destruction somewhat like a wishing star. I can’t remember the details but I would like very much to find this story. Can you help?

What do you folks say?

  1. It doesn’t ring any immediate bells.

    I’ll start thumbing through my Adventure issues.
