Once a hunter was passing by a dense forest. He had his gun with him. When he was a little deep in the forest, he saw a pigeon perched on a branch of a tree.
He aimed at the pigeon with his gun and was about to pull the trigger when a snake from nowhere came behind him and bit him. The hunter could not shoot his prey and fell down. The effect of the snake’s venom was so strong that within no time his body began turning blue and he started rolling on the ground, frothing at his mouth.
While dying he thought to himself, “The snake has done to me what I was going to do to the innocent pigeon.”

Moral—Unnecessarily harming someone, never bears good results.
