Involuntary reptile-slaughter
One day, some innocent kid came across a creature that he thought was a turtle. Being the dumb kid he was, he decided to lend a hand by tossing the turtle into the water. As we all know, turtles belong in the water, and that land is only for bipedal mammals.
What the kid didn’t know was that the creature he tossed into the lake wasn’t a turtle. It was a freaking tortoise, and tortoises don’t swim. While he had good intentions (can we call it good if you’re forcing an animal into the water?), he undoubtedly ended up killing that poor tortoise.
