It works just fine if we consider this a war. They are permanently removed from the enemy's strength, even if they are still technically alive. Kite's team is mainly fighting against time here, seeing as they hope to reach the queen before the king is born. These low-level enemy grunts were nothing but a delay (even the enemy commanders considered them such), and in that sense being dead or dying changes nothing. They weren't really individuals worth noting.
I bet Kite will later regret allowing Rammot to escape, though, not finishing him off immediately when things started to go wrong.
