Exploited: While Maxine is distracted, one of the demons sneaks past it and uses it to wipe out his species.
"It's my duty to defend humanity. I'm going through with this."
Maxine destroys the MacGuffin with her own hands as soon as she gets a hold of it. "I don't care if this would have been a much simpler way - I will not stoop to their level of evil in fighting evil."
Discussed: "Look, we've already tried reasoning with them. If we don't do this, we might as well be taking their side." "I know, but that doesn't make it any easier."
Nicole:Remarkable how much you learn about someone from one little decision.
Oscar:I'd hardly call choosing whether to sacrifice your character or multitudes of lives "little".
Deconstructed: Lucas calls Maxine out on her hypocrisy for hunting demons but being unwilling to destroy them as a race. This leaves Maxine with two choices: either use the MacGuffin and bear the moral consequences, or stop fighting and sit at home drowning her sorrows while the Legions of Hell roam the earth.
Played For Laughs: Maxine agonises over whether or not to wash her hands with antibacterial soap, since she sees it as mass murder.
Played For Drama: After much hesitation, Maxine activates the MacGuffin and kills all the demons. She then decides "there's one last demon I need to deal with", goes away and turns her gunon herself.
