Immediately after Bender joined college he falls in with a bad crowd and drops out of college. After shortly living the life of thug, a drug addict, a prostitute and being beaten up by the robot mafia, for owing them money, Bender hits rock bottom. When he tried to rob a group of girl scouts and failed he got prosecuted in court but released due to not being responsible for his actions since robots don't have a free will. Depressed about the fact that his decisions don't really matter since they are predeterministic he goes on a soul searching trip and joins a monastery to embrace his faith. But as soon as he finds out all robots have an empty free will slot he goes on a search of the inventor of this so called "free will unit". Written by

A robot free will unit? Impossible! And even if it were possible, which it's not, it would still be inconceivable. Which it is!
