I do love that he accepted death "because rules are very important" Such a man of ethics and stoicism.
He is the type of teacher that you hate as a kid but really respect and are grateful for when you grow up.
@dogber7 Depends on if the Death Note and the Instant Death attack only attacks the body or if it can target a soul directly and destroy it. Remember the Grim Reaper kills the body but harvests the intact and unharmed soul.
