I know that in my case even when I was very young and became aware of what death was I found comfort in the thought of ceasing to exist, I've always preferred the sound of the true peace of non-existence to having the ability to suffer in this meaningless, cruel and dreadful existence.
But only never existing is true perfection to me, existence is just a harmful, futile imposistion that causes nothing but endless suffering so of course only wanting death makes sense to me, my wish to die is a result of becoming aware of how truly undesirable existence is. I simply don't want to suffer in any way and in existence there is endless potential for suffering, pain and torture, I despise existence, it's evil to me.
