"as soon as the aprentice can take on the master he does it.if maul and dooku didnt try to kill sidious is because they were weaker.that how it works for the sith" Not true. Because Darth Plagueis was stronger than, Sidious. Darth Sidious killed him in his sleep...remember? So it don't always work like that. He just had the guts to kill his master in his sleep. Maul and Dooku didn't.
