Death's Favorite Child

He was a highly trained killer, serving a 1000-year-old secret organization on Earth. He was betrayed by the people he served all his life and left for dead. His entire team gone.

He took his revenge, reducing them to ashes, and died in the process.

God of Death took a liking to him and named him Death's Favorite Child. He was reincarnated in another world to reap souls. The last thing he was told by GoD was:

"Go my Boy, live your new life and be the Reaper of Life. You can be the Hero that rids the world of all evil or the villain that destroys the world. Death does not discriminate, Death does not judge, Death is always by your side!"

Now in another world, with strange abilities related to Death and a past life history of violence and killing. What road will he choose?

Oh, and it seems a ghost from his past piggybacked through his reincarnation and got stuck with him...
