 No one can predict with 100% certainty who will live and who will die.

100% of people will die. At least so far...

Suicide is reckless, because it will inherently cost another person money, suffering and time dealing with it.

So are a great many things.


Assisted suicide as the thin end of the wedge for nazism? Now that you mention it Hitler did commit sucicide...

Mistakes happen? People sometimes die due to surgery and medication mix ups. Better stop doing those, its playing god anyway.

At best these are arguments to not have a shitty system.

People do have the right to decide to end their lives, they do it all the time. THey sign DNRs, they refuse treatment ect. 

Also you cannot practically stop people from taking their own lives. They shoot themselves, jump of bridges, hang themselves ect. You cant stop suicide. If you want to argue that more money and effort should go into mental health and education to prevent it, great i'm on board. But if someone honestly wants to end their life the least we can do is let them do it with a little dignity. Also the success rate will go WAY up, since that is apparently one of your objections.
