When I was nine I killed a common frog. A typical backyard pool set on concrete. A frog leaping around on soft grass.
I picked up frog with intentions of killing frog. I used froggy as a slip and slide. Until he was dead my logic for killing mr.croaker. there are millions of frogs, and this would not effect balance. Tadpoles die or become food source. My logic, I have fed ants. I didnt commit murder.
