If you are referring to the fight on Coruscant, the goal was not to beat Jacen. The goal was to make it look like an assassination attempt and plant a tracking device on him. Kyle was not out to kill him. You can't use this as an example.
Exactly this. Everyone knows that Katarn could wipe Caedus out any day of the week. Remember, there is NO Sith Order. Just a list of Sith that Kyle allows to live....for now.
