[PhasmaFelis]

People who've made a firm decision that dying is the best thing for them to do don't call hotlines to get talked out of it. Nothing stopped any of those people from trying again later, either, if they decided that holding off had been the wrong decision. There's plenty of stories from people who e.g. jumped off a bridge but survived, who were filled with regret as soon as their feet left the platform. The fact is that suicidal impulses are often acute and transitory.

People should have the right to die, but you're basically saying that people shouldn't be allowed the option of talking things over with a sympathetic listener before making a final decision.
