From an interview in the Sunday Times, October 2nd, 2011.
I never thought I was doing anyone a favour by bringing children into the world. With people as cruel to each other as they are, it’s a terrible proposition. The best of lives are sad and tragic. The best of them. My general conclusion is that it’s not a nice thing to do. The world doesn’t need it. The kid doesn’t need it.
When the interviewer, obviously a little incredulous, responded by saying that surely a man of Allen’s wealth could guarantee a child a good life, Woody answered
I can’t guarantee a child anything. I can’t guarantee that I was around five minutes after he or she was born.
Good man, Woody!
