I Was Reading About Boom Boom Mancini

I was reading about the fight between Ray "Boom Boom" Mancini and the Koreon boxer Du-Koo Kim. If you don't know Mancini beat Kim in 12 rounds and after the fight Kim slipped into a coma and died. The most amazing thing is that in his hotel room the night before the fight Kim wrote a note to himself that said, "Kill or be killed."
Is it really sick that this story makes me want to be a boxer?
