Tao image - The Jedi Order

Following the devastation of Shumari, Vader attempted to train Tao in the ways of the dark side, but he was unable to get the boy to fully submit to his anger. Meanwhile, Vader was called away to deal with the Battle of Yavin which saw the destruction of the Death Star superweapon. Upon returning to Coruscant, the Dark Lord was faced with the wrath of his own Master, Emperor Palpatine, who was displeased that Vader was unable to stop the Death Star from being destroyed. At the conclusion of this meeting, Vader returned to his meditation chamber feeling angry and frustrated; there, Tao confronted the Sith Lord. Fuming at what had transpired in the Yavin system, Vader demanded that Tao attack him with all his anger in an attempt to strike him down. Tao, however, could not bring himself to totally give into rage, earning his Master's disapproval at lacking sufficient hatred to be a Sith. Attempting to push Tao over the edge, Vader reminded his young apprentice of all he had taken away from him—his homeworld, his Master, his friends, and his family. Despite Vader's goading, Tao could not understand why his master was demanding such anger from him. Vader's explanation, that only the strong deserved to live, led Tao to vow that he would become strong.[1]
