Good people do not need laws to tell them to act responsibly, while bad people will find a way around laws.
Whether or not we have hope depends on two dimensions of our explanatory style; pervasiveness and permanence. Finding temporary and specific causes for misfortune is the art of hope: Temporary causes limit helplessness in time, and specific causes limit helplessness to the original situation. On the other hand, permanent causes produce helplessness far into the future, and universal causes spread helplessness through all your endeavors. Finding permanent and universal causes for misfortune is the practice of despair... The optimistic style of explaining good events is the opposite of that used for bad events: It's internal rather than external. People who believe they cause good things tend to like themselves better than people who believe good things come from other people or circumstances.
