A key point to that story  is that Jesus is God. The embodiment of God on earth. So, the focus isn't just atonement but is that God dwelt among the people and experienced rejection and death. Some Christian groups (non trinitarian especially) focus on the atonement of sins heavily, and some - not as much. There are as many ways to interpret it as there are denominations (and likely more). So it is hard to paint it all with one broad stroke.
