A new choice of original sin:Murder of a brother

As I was thinking about original sin and its definition which is defined. the sin of Eve tempting Adam to eat the apple and thus they reached maturity and made love,worked and produced children.That doesn’t seen sinfull except they were disobeying God.

To me the murder of Abel by Cain was the first real act of wickedness.And family and national feuds still occur in our world.The children are  jealous of each other.Some parents can deal with this,but many can’t.They may punish the older child but not let them talk about how they feel.

I don’t think sexual desire in innately sinful; what counts is how we treat other people.Sex can be exploitative or loving or greedy..Nature means for us to reproduce as if  we don’t our race will die out;and with the current political problems the world may end anyway and we will all be like Cain.
