Assisted dying (the option) is an incentive to suicide

When assisted dying is possible, this will seduce people to commit suicide. Assisted dying is only the first step to more (f.i. euthanasia, more lonely suicides). Once it’s allowed, there will be more and more cases (Pandora’s Box argument, voluntary death considered to be contagious) to an intolerably high level (thus costing even more lives).
