Kurt Vonnegut: Trending quotes

In A Man Without a Country (2005) p. 80–81 Vonnegut makes a very similar statement:
God Bless You, Dr. Kevorkian (1999)
Context: About belief or lack of belief in an afterlife: Some of you may know that I am neither Christian nor Jewish nor Buddhist, nor a conventionally religious person of any sort.
I am a humanist, which means, in part, that I have tried to behave decently without any expectation of rewards or punishments after I'm dead. My German-American ancestors, the earliest of whom settled in our Middle West about the time of our Civil War, called themselves "Freethinkers," which is the same sort of thing. My great grandfather Clemens Vonnegut wrote, for example, "If what Jesus said was good, what can it matter whether he was God or not?"
I myself have written, "If it weren't for the message of mercy and pity in Jesus' Sermon on the Mount, I wouldn't want to be a human being. I would just as soon be a rattlesnake."

As quoted in "An Interview with Kurt Vonnegut, Jr., Carey Horwitz, Library Journal, Apr. 15, 1973: 1131
Various interviews
Context: All these people talk so eloquently about getting back to good old-fashioned values. Well, as an old poop I can remember back to when we had those old-fashioned values, and I say let's get back to the good old-fashioned First Amendment of the good old-fashioned Constitution of the United States—and to hell with the censors! Give me knowledge or give me death!

A Man Without a Country (2005)

the conscience shrieks, in effect, to all the other mental processes. The other processes try it for a while, note that the conscience is unappeased, that it continues to shriek, and they note, too, that the outside world has not been even microscopically improved by the unselfish acts the conscience has demanded. They rebel at last. They pitch the tyrannous conscience down an oubliette, weld shut the manhole cover of that dark dungeon. They can hear the conscience no more. In the sweet silence, the mental processes look about for a new leader, and the leader most prompt to appear whenever the conscience is stilled, Enlightened Self-interest, does appear. Enlightened Self-interest gives them a flag, which they adore on sight. It is essentially the black and white Jolly Roger, with these words written beneath the skull and crossbones, 'The hell with you, Jack, I've got mine!"
God Bless You, Mr. Rosewater (1965)

In A Man Without a Country (2005) p. 80–81 Vonnegut makes a very similar statement:
How do humanists feel about Jesus? I say of Jesus, as all humanists do. "If what he said is good, and so much of it is absolutely beautiful, what does it matter if he was God or not?"
But if Christ hadn't delivered the Sermon on the Mount, with its message of mercy and pity, I wouldn't want to be a human being.
I'd just as soon be a rattlesnake.
God Bless You, Dr. Kevorkian (1999)
