I feel that suicide in general is not a good thing. People see it as the only way out, the only exit. However, assisted suicide is probably the saddest thing ever. If one wants to commit suicide, well, that's themself. But don't bring another person into it.
If someone has an incurable disease, and is suffering, yes!!! Why go on for years, when there is no hope. I watched my mother suffer with cancer, inoperable, no hope what so ever, waste away to seventy pounds!!! I wouldn't let a dog suffer like that, believe me, if there was a pill, I could have given her, I would have.
