[After]
Currently? Nothing, save one less student who refuses to learn. [He says it so easily.] But you assume your attacker would even need that much of a reason. I've killed hundreds, one more death on my toll would mean little.
[Untrue, but he is not the man he was before he died. That man would have cared, would have been as efficient as possible. He has no reasons to kill now, and does not intend to do so, but should he choose to kill would he need a reason?]
You should not expect your opponent to put the same value on life that you do. You should not assume that even if they do, it will prevent them from taking that strike to kill. Many do not get the chance to remedy such a mistake.
