It was probably a training excercise, but as Kenpachi takes fighting so seriously, Unohana the most diabolical criminal, most likely a murderer, would be the best to teach him how to kill. She has alot of knowhow about swordplay so says shunsui, but like i was saying as kenpachi takes it so seriously who better than to teach him hard swordplay than the only person who could withstand his attacks? But their rivalled past would make it more serious. To put it simply, who better the train a swordsman, than the best swordsman? Who better the train someone to kill, than the best killer? And the death part, if two people loved fighting so much, why would they ever want to stop? He probably meant it like they will wear each other down until one is left standing due to their bloodlust and stamina, than one standing over the other who lay there unconcious and finish them off.
