I'm with you on this, misko... I'm actually ambivalent on the subject of suicide. It's one of those topics that brings out the absurdist in me. There's no absolute that can be fallen back on here that is wholly consistent, at least without bringing religion into it. To argue that there is any value in life beyond what one feels for it themselves is to ascribe some source of that value which is absolute, beyond human experience. I don't believe in such a thing.
This is one of those subjects that lays bare the random absurdity of existence to me. The only thing which makes life more than some random absurdity is our own agency, and our own ability to explore our feelings about the situation on our own terms. One of the most sacrosanct aspects of the human experience to me is the struggle to find and create value in ourselves by our own self-originated ideas of value, and if everyone succeeded, it wouldn't really be all that special, would it? It's for this reason that harming one another should be avoided, because it violates that self-determination... but respecting someone's right to harm themselves is the other side of that coin, even if it's sad. We don't have the right to tell someone else what their life is worth. We don't even have the ABILITY. We can express it. We can physically enforce it by removing the means to self-harm (including psychological). But we can't replace someone else's feelings about their own life with our own, and it would be wrong if we could.
Otherwise, we'd outlaw shit like smoking, soda, dangerous sports, etc... right? Because we can easily argue that those are just different ways to kill oneself, or express a devaluation of one's own life.
It also bothers me when people bring "chemicals" into this. It's all chemicals. I'm not saying that medical depression isn't a real thing and a problem. But to automatically disregard negative experiences and motives as "chemicals" once they reach a certain threshold that correlates with a specific action you don't want to happen, it invalidates all of human experience. It's all chemicals. All our thoughts and feelings. And without the absolute source of value from beyond human experience as I mentioned before, we could assign invalidation of self-determination at any point because "it's not really them it's these chemicals" and the validity would be objectively equal. Yeah, we can't ignore that there is a hardware aspect to our physical make-up that can be fucked up, and it's ok if someone decides for themselves that they want to take a hardware approach to fixing it (medication to address chemical issues). But to say "if someone wants to hurt themselves, we have to save them from those chemicals" is to decide that your own feelings about the lives of others are the determining factor as to whether something is genuine human experience or "chemicals".
Here's to those who have decided to leave, including a friend who toughed out 30 years of cerebral palsy and left a 1 year old child. I don't hold it against them, and I don't regard them as machines that malfunctioned.
