Death is thought to be just an ending; a full stop to your life. However its more a semi-colon for your soul in that your soul could stop, but it doesn't; it goes on.
Or it would if certain sentient beings would allow it to.
My job is to gather your soul and take you to the other side where you face Judgement. Once judged you go Up or Down; there is no left or right for humans. Strictly speaking, left and right are reserved for animal souls. The only other change that can happen is Reapers.
Reapers don't get a choice in what we become. We're given this charge as penance for crimes against us throughout our life. Reaping is given when Downstairs isn't an option, more of a privilege and even when our penance is up there's no guarantee we won't still go down. That's the catch of the sadistic bastard you call God. He'll give you the glimmer of hope but yank it from you without batting an eye. This is the same prick who started Armageddon because he was bored.
You see, God isn't this wonderful, loving, beautiful creature that humans have come up with, (honestly, where you people get these ideas is beyond me,) He has a plot going to harvest souls in such a magnitude that would leave no room for Death. You see, souls are used as a kind of currency in the cosmos. The more souls he consumes, the stronger he becomes. The stronger he becomes, the better able he is to control and manipulate time and space to where the Infinities bow down to him. When the Infinities bow to anything, that isn't good news for any of the worlds in the solar systems and beyond.
When that happens, everything anyone has ever known will cease to exist, and then it truly will be the definition Humans have come up with: the permanent ending of vital processes.
All Endings starts with Beginnings; remember that as you fight to keep your souls safe and the world you love in one piece.
