They say that the Lion holds nothing back, even when hunting rabbits. I do not know if Rabbits and Lions actually interact, but that is besides the point.
Besides, I don't *try* to kill the people I train with.
I simply miscalculate my own immense power, coupled with overestimating the limits of my partner. They die because of human error.
It's unfortunate, but it happens.
...With that said, I like to think that even these failures are honoring them.
Think about it. A desperate battle where they are forced to hold nothing back, to evolve as warriors or perish...I am helping to forge the blade of their being with every blow. They shall be made into true blades, or be shattered.
By having a contest where they feel 'safe' or 'not in mortal peril' am I not robbing them of the chance to reach the Apex manifestation of their potential? Who am I to deny them such a thing?
And who are they to deny me? Each being that falls to my fist teaches me yet another lesson. About the strength of Miburo and about the frailty of man.
It's a honor for both myself, and for my dearly departed training partner.
Of course, you made mention of teacher...So that is a tad different.
I mean, the one who is Miburo Hunter, becomes Miburo Hunter once the one who came before him perishes, relinquishes the title, or is defeated in glorious combat. Of course, no Miburo surrenders his title to his student directly (outside of very specific instances, don't ask why I am Miburo and not Miburo Hunter)so death is a consequence.
This glorious cycle must be upheld (usually) and is not far from teacher/student relationship. When one has reached the summit of knowledge as a student, how else can on see how one measure's up to their master? And how can they be certain they have produced a student who can both carry on, and exceed their legacy? A simple training exercise will not do.
One must come to rend body and soul apart, and to be torn asunder in turn. This is how both master and student are satisfied.
But, usually those days are many many moons away....And I'm a crappy student, so I don't care if my masters are happy, so this doesn't happen that often.
...Yet.
