Look back in anger.

It's my own decision entirely. In fact, she's just been trying to talk me out of it. It's just that suddenly, tonight, I see what I have really known all along. That you can't be happy when what you're doing is wrong, or hurting someone else. I suppose it could never have worked, anyway, but I do love you, Jimmy. I shall never love anyone as I have loved you. But I can't go on. I can't take part - in all that suffering. I can't!

They all want to escape from the pain of being alive. And, most of all, from love.
