Humans, who are initially neutral, can stay neutral, but can also go both evil or good.
Liches can remain neutral, but also go both good and evil.
Starting allignment of a lich will remain same as human player had just before he transformed.
Angels will have stat changes when they transform.
Abominations will have stat changes when they transform.
Liches will get stat changes when they transform.
Stats don't just when your alignment changes, they only change once when your body form transforms.
Transformations are, for now, irreversable!
