My apologies for any inconvenience. Fear is the path to the darkside. Fear leads to anger.
Anger leads to hate.
Hate leads to suffering. Truman standing at edge of water afraid to cross because of implanted memory of father's death. After Mufasa is killed, Simba runs away to avoid becoming the king of the lion kingdom. It is Simba's fear of inadequacy that keeps him from accepting his role as king. The premise is that most decisions are made out of fear.
