I don't think you know the whole story and you think you know what happens inside peoples heads. Steve jobs had pancreatic cancer with a 5 year survival rate of 10% for eight years, he already beat the odds. He had a kind of cancer computer fabricators got in the 70s and ravaged grey beard engineers across silicon valley.
You really have no idea what you are talking about, what it is like to be sick and what chemo does to you. It is their right not to seek treatment and to go out with dignity if that is their decision and that doesn't make them a moron.
You don't fucking know that! He had a terminal illness which is terminal and it was his right to deal with that and treat it on his own terms, not yours. You don't know everything. I too have a terminal illness and you can't force me to die in a fucking hospital hooked to machines with incessant beeping and exploited nurses who need to to take a nap. I don't want them to drain everything so my wife gets nothing but an insurance pay out. I want to die at home with my wife and my cat and all my shit on my own fucking terms and fuck you if you say anything else.
Literally fuck you for denigrating sick people and terminal people for not doing what you want them to do with your ideas and shaming them. You are a fucking asshole.
