A Christian, too, will remember that Jesus wanted people to be free to make the wrong choice, or they would not be free to truly choose the right one. If the government could force you to write an article supporting something you don't believe in, then you wouldn't really have freedom of speech, even if it didn't actually ban speech. You're absolutely correct. In fact, I guarantee right now that someone will try to abuse it. How about telephones.
People do sometimes try to kill others with their car.
The fact that people might abuse something is never a reason to take away the choice from everyone who will not abuse it, of course. The solution, of course, is just prohibit abuses, just like we forbid robbery and rape instead of banning property and sex. It's already illegal to kill someone who doesn't want to be killed. All we need to do officially acknowledge that it is legal for someone to choose to die. The idea that being able to use a pill should be banned just because sticking a plastic bag over your head sounds horrible is just insane.
