Dr. Loomis decides to end it all by blowing himself and Myers to kingdom come via some loose oxygen tanks, but not before getting Laurie out of the room. Then he takes out his lighter, and:
Dr. Loomis: It's time, Michael. *KA-BOOM*
Villainous example comes in right after the said explosion, as burning Michael walks Out of the Inferno and collapses on the ground before reaching Laurie. Even in the brink of (temporary) death he was aiming to kill her.
