I think about this quite a lot, actually.
I don't think I fear death, itself. I do believe in paradise after death, but I also have many doubts all the time about it. I mean, we don't actually know, do we? I cannot fathom either ceasing to exist, nor living eternally.
But, the thought of a paradise, where I can see my loved ones again, makes me at peace with death.
I'm also not really afraid of dying at the moment. I mean, what'll happen will happen, so I see no point of fearing it until it does. As I grow older, I shall probably start worrying about a painful death, but at the moment, I do not.
What worries me is any pain that I will leave behind. Anyone who will cry themselves to sleep, missing me. Anyone that my death shall cause pain to. That's what makes me afraid. I don't want to inflict that kind of pain into anyone.
