Your honour, this is clearly a case of innocence by reason of temporary insanity. Mr. Kwan was obviously under extreme duress, living a slave's life, and clearly he just snapped, and in a moment of rage, threw off the shackles of oppression. Mr. Kwan is a victim your honour, not a murderer. If anything, he's a hero.
I'm really sorry to make light of a man's death, but this is absolutely poetic justice to me. I hope Brother Kwan escaped.
Mina.
