I think it's absurd to be anti-suicide when we are destined for nowhere but to die anyway, all that existence is, is a futile and meaningless distraction from the fact that our existences are impermanent and will eventually be forgotten about. I could never see any benefit to delaying the inevitable and suffering more in the process, we are all just waiting around to die, existing leads to nothing other than being tormented by old age and the thought of such a thing repulses me.
But it's undeniable that death is the most normal thing, so to say that suicide is "wrong" makes little sense when death erases everything for us and there's no escaping death anyway, I think it's perfectly logical wishing to exit on our own terms, permanently being free from existence is the only thing that appeals to me.
