Throughout time and space, different peoples have had different ideas of which acts are moral and which are not. People take the moral instinct, and come to different conclusions.
Romans tended to think that those with power had the right to use it and to not care about the downtrodden. Charity was done to make you look good, not because helping people in and of itself is a good thing. Charity was focused on helping your kin and allies, not human beings because all humans have value.
Jews thought you should help your neighbor, but not all humans on Earth.
Jesus taught that everyone matters.
Jesus appeared to really think that a rich person could not get into Heaven. Modern Christians find excuses to ignore that. Bible scholar Bart Ehrman said that when Jesus said, with God, all things are possible, he meant God could change rich people’s hearts, convincing them to give away their wealth.
Jesus taught that you don’t need atonement to be forgiven. But his followers thought his death was an act of atonement. So, Jesus was crucified partially for teaching that you don’t need atonement, then his followers codified Jesus’s death as an atonement!
