It's wrong to wish death upon other people.
Bob and Tom are having a fight over the ownership of a used car, and one night Tom comes and tows the car to his house.
Bob has to decide what to do about Tom and the car.
Bob asks Tom if they can sit down and have a rational conversation about the car, so that they can move on with their friendship.
Bob calls Tom on the phone and tells him that he hopes something tragic happens and Tom dies.
Tom feels a sense of obligation to talk about the conflict and Bob is happy to get his grievances out in the open.
Tom feels stunned and shocked by the call and Bob feels ashamed of himself for saying something so like that over a car.
