William Munny "Clint Eastwood" in "Unforgiven" going into the saloon at Big Whiskey to kill the people who hung a sign on his friend, Ned (Morgan Freeman). When the conversation comes to this dialogue betweeen Little Bill Daggett (Gene Hackman) and Munny I think we see the whole of the ugly nature of killing and murder in just a few sentences. The best part is where they say:
"Little Bill Daggett: You'd be William Munny out of Missouri. Killer of women and children.
Will Munny: That's right. I've killed women and children. I've killed just about everything that walks or crawled at one time or another. And I'm here to kill you, Little Bill, for what you did to Ned."
The thing that really clinches the whole deal is that after the murderous Munny kills half the bar and threatens the entire town the one prostitute who was responsible for hiring them to kill looks at Eastwood riding out of town on his big white horse and she's thinking he's her knight in shining armor. It's freaking brilliant stuff. It's the best movie of all time IMO. It explores the nature of man in ways most movies never even dream of. It shows how it takes a cold blooded, heartless monster of a human to kill the way some do but at the same time it shows that even a man like that can be transformed even if he does fall back into his old ways. But he plays the role of hero in that moment.
That movie is true art IMO. It fully explores the nature of humans that kill without compunction. It is just a brilliant movie IMO. The best ever. It shows how being cool under fire will win out over being a fast draw with a gun but that being fast certainly helps if you're cool too. The people that panic are often the ones that die. It's the people that can control their fear that live. Some just don't care if they live or die. Some just think that no one will ever get them. The best movie ever made IMO.
