no, if I get drunk than that's my decission (with all due respect); If someone else wants to end my live, and is able to apply all sort of trickeries to argue that this is in conformance with the law, then that's a different thing.
Again, the law you're after here is preventing elder abuse. This is indeed something we should pay great attention to and try as best we can to carry out the wishes of the elderly. This abuse is no uncommon, even if it's comparatively benign by changing estate inheritance at the end of life for instance.
It really has nothing to do with assisted suicide.
Yet, we don’t shut down every coal power plant because it’s useful just as we don’t ban cars etc. The benefits of assisted suicide are similarly significant and therefore worth it.
You're saying this as if we're talking about involuntary euthanasia.
