He would wish he had not been born ... is what he thinks when he feels bad.
Because of a fight, a lack of love, a deception, an injustice.
If he had known that living would involve so many negative emotions, he would never have wanted it.
He would rather be a plant or an animal, any living being that is not aware of good or evil, that only wants to survive.
But not, the one born as a human being, thinking and consenting, able to feel and suffer, to be hurt and humiliated.
why? He asks, why have to endure that day after day?
Why not just end their existence? Why not just jump out of a building or drown in the tub?
Because he is afraid to die.
He wants it, but he fears him, he fears what he is after death.
He knows well that there is no heaven or hell, he relies on science.
He knows what brain death is, but he is afraid to experience it.
Knowing that your body is slowly going out, your functions will slowly go away ...
He thinks, that maybe those thoughts will go away if only someone.
