Karma and the frogs

It’s a wet night, so there’s more frogs on the road than I’ve seen all spring. I try to avoid hitting frogs as much as I can, but then I started thinking. If you were born a frog due to your past karma, and I hit the frog, would I have freed the frog from its existence so then it would be free to move up a step in its next reincarnation, OR would I be dooming it to be reincarnated yet another time to learn the lessons it had yet to learn as a frog?

This is why I try to avoid hitting frogs, it’s too much responsibility otherwise.
