How do you become an angel?

How do you become an angel, after a life of darkness? I don't know.

He was a blinding light in the dark. The stereotypical blond, blue- eyed, white-clad, cute little boy. With iridescent wings. Caught in the night of terror and despair.
I was there, watching him. Watching my brethren toying with him. Tormenting him. The same game, over and over again, as I stood there, watching. Always it had brought me pleasure, seeing such agony on innocent faces. It was just the way I was. Human nature, you could say. Except that I was not human. And I would not blame my actions on something other than me. We were creatures. Evil creatures of the night. As dark as that angel was light.
I watched as the shadows crept closer and closer to the boy's beautiful wings, as their nails tried to tear into the feathers.
I watched as his face contorted in delicious pain and fear, his eyes wide, as was his mouth, screaming a silent plea for mercy.
But the fallen have no mercy. This is their life. Pain is their
quintessence.
I watched as a tear slipped from under his lashes, gleaming blood red in the burning fires, as was the blood running down his tattered wings.
I watched as he sank to his knees, the agony of hundreds of cuts bleeding him out, sending irregular tremors through his battered body.
He wouldn't last long now. A flame snuffed out by a wind that was in the mood for play.
I watched as the insane smiles of my people widened in anticipation, feeling mine tug up as well, as the heat became almost unbearable, even for us.
I watched as he opened his eyes one last time. His blue, blue eyes, full of fear. Full of pain. Full of questions and incomprehension.

I watched him as he watched me.

And I took him away.
Away from the fear, the pain, the questions.
Away from the fire, the darkness, and my cursing kin.

Out of hell.
And although I could never reach Heaven, I hoped the warm
embrace of my arms would be enough of a light to make him alright.

Enough to make him heal.
Enough to make him open his eyes and smile.
Enough to make him soar again.

Enough to make him forgive me.

Someday.
