One-to-one

Some months ago I was in an electronic party, while on a wall of that club a movie was being projected. I could not find out its name, thus, I went to talk with the Dj to ask him what the name was…”Party Monster”.
This movie tells the story of Michael Alig, a guy who organized huge and fabulous parties in New York; therefore it would be great if I could ask him why he invented such weird electronic parties, and certainly, I’d go to his parties, without trying drugs as he did.
Apart from him, I would like to meet Benedict XVI…why? I’d ask him if god agrees with him, why Catholic Church does not donate its money, to eradicate poverty and famine in Africa and America.
Two different characters that do different things, one of them made people have fun, the other one tries to manage his flock of sheep. Now, try to guess or to find out who is a murderer.
