Assisted suicide should be available for anybody, regardless of their reasons.
Nobody agreed to be born in the first place. We've had this world and society imposed of us. By being born we, most of us, are essentially forced into accepting that we will have a life of misery, and not only that, we will be forced to work, making other assholes rich in the meantime, simply to survive. It's bullshit. It's barely a few steps away from slavery.
In law you cannot be held to a contract if you were misled into signing it. Yet we are supposed to just accept a life of pain and suffering into which we were given no choice? Seriously?
Fuck that.
