who says anything about losing the will to fight? quite the contrary... the fact that they are so weak by the time of prophecy that they need help from midway pilots indicates that instead of continuing a futile fight with humans with their forces so severely hurt, they instead turned on eachother to vie for rulership of the empire. Its not known who or if there is a new kilrathi emperor. Malek certainly was a good candidate for taking advantage of his position to become the next emperor. My guess is that they went back to the old methods kilrathi warlord versus kilrathi warlord for prestige.
