Consider this hypothetical scenario. Bob has taken his four-wheel-drive Jeep out into the desert to explore on a hot sunny Sunday. But his two cousins want to see him dead. Mary has put poison in Bob’s five-gallon canteen. Steve, not knowing of Mary's plans, has put a very small hole in the canteen. Bob’s car breaks down. He’s getting hot and thirsty. His cell phone doesn’t work because he forgot to recharge it. He goes to get some water and finds the canteen empty. Then Bob dies. Overcome by guilt later in the year, both Mary and Steve confess. Who do you think should be blamed for causing Bob’s death?
