The Scorpion and the Turtle

Theres a fable about a Scorpion and a Turtle.

The scorpion needed to cross a river. He asked the turtle to give him a ride on his back.

The turtle said~

How do I know you will not sting me?

The scorpion replied that it would be suicidal to do so because then they would both drown.

The turtle saw the logic and agreed to ferry the scorpion.

Halfway across the river, the turtle felt a sharp sting.

As they sank under the water, the turtle gasped

Why did you do that? Now we will both die.

I can not help it.
