It took a few lives to realize that He meant I would wander through multiple lives, across the world, until the end of time. And when people started writing down what they were told was a true and accurate description of the stories that came before them, I realized that my story had been changed, and anything from my side had been taken out, because He wanted an example. I was the person people could point to and claim to be evil, to be blamed for things like murder and for people to see as something to be held up as 'do not be like this person'.
As for Abel... his soul was shattered when I killed him, and it was scattered amongst humanity. Various people inherited shards of his soul. I learned even later that Abel wasn't originally his own soul anyway - he was a split off portion of a demon called Bel that the one called 'God' defeated a long time ago. The demons called Abel the 'Bel of the Human World'. A human who has a shard of Abel in them has the potential to absorb the powers of another Bel demon if they defeat that demon - just as the other Bel demons would absorb the power of another Bel demon if they defeated them. In this way, Bel would become whole again, and become the King of Demons once more.
Of course... the fight for that was a long way off. And should any other Bel demon win, well... you can imagine the kind of ruler most demons would make. There's only one acceptable winner of that fight, for the sake of humanity.
