It’s kinda like abortion. It used to be that abortion was totally illegal. Then they said, we’ll allow abortion to protect the health of the mother. Then they said, we’ll also allow abortion in cases of rape or incest.
Next thing you knew, abortion was available in every situation, and millions of women were getting abortions. It turned out, if you allow abortion in any situation at all (e.g. if the kid has Down’s syndrome), then suddenly all women are demanding the right to an abortion if they want one, even if their kid isn’t defective. Once you open the door just a crack, by making one exception, then everyone else wants an exception made for them too.
It’s the same way with suicide. If you let one guy who’s stuck in a wheelchair and totally miserable kill himself, then suddenly everyone else is going to want to be allowed to have suicide rights too. Teenagers who broke up with their girlfriend will want to be allowed to commit suicide, and pretty soon, millions of people will be killing themselves.
So, just like the Catholic Chuch says, “Abortion is always sinful, even if we already know the kid is going to be born brain-damaged,” people also say, “Suicide is always wrong, even if your life seems totally fucked up and not headed for any improvement.” They don’t want to open the door even a crack, to allowing the idea that maybe some people would be better off dead; because once they do that, they’re going to be overwhelmed with people asking for the right to die, and claiming their circumstances would justify suicide.
So what they do, is say, “Everyone’s life is precious, and no one should kill themselves. There’s always hope for everyone,” even though they know that’s not always true. It’s like how the Catholics say, “Every baby is sacred, even if it’s going to be born blind and retarded and half-paralyzed for life and will cost the taxpayers hundreds of thousands of dollars.”
So it’s basically the same concept as, “The reason I’m not going to share my potato chips with you, is that if I gave one to you, I’d have to give one to everybody else.”
If we gave suicide to one person, we’d have to give it to everybody else.
