The Scorpion and the Frog is an animal fable which teaches that vicious people cannot resist hurting others even when it is not in their own interests. This fable seems to have emerged in Russia in the early 20th century.
Synopsis
A scorpion wants to cross a river but cannot swim, so it asks a frog to carry it across. The frog hesitates, afraid that the scorpion might sting it, but the scorpion promises not to, pointing out that it would drown if it killed the frog in the middle of the river. The frog considers this argument sensible and agrees to transport the scorpion. Midway across the river, the scorpion stings the frog anyway, dooming them both. The dying frog asks the scorpion why it stung despite knowing the consequence, to which the scorpion replies: "I am sorry, but I couldn't resist the urge. It's in my nature."
