That said, in the end "new" Billy does in fact come to care about and have empathy with others, share the power with the little guys, and without saying it, you realize it's what he really wanted, and what separates him from Teth(the fallen champion) which speaks to and is true to the classic characters.
Classic origin was in 3-4 pages, or 2 panels looking at the Wizard's "historama". It's purely plot driven, You are just told who Billy was, there is no character growth.
This new tale, Billy isn't just born that way, he has to get there, gives him a bit of an arc before he becomes that character.
