Your point being? Malak was one guy, not a thousand. He was also inferior to Revan. Yes Malak failed, but at least he accepted that. Kun just clung onto to life, refusing to admit he was a defeat.
Revan clearly could not handle thousands of Jedi at once. Actually our characters also kicked his *** in the Foundry.
Sith should be eager to kill and surpass their master, but Malak turned to a weak man in the end. A true Sith should try the best to fight back, at least not lose the spirit.
