To a large extent, circumstances and intent determine whether or not an act is evil, or the extent of that evil.

And no where do I state that an evil person cannot be rehabilitated.

Polanski's actions: raping a child, fleeing to avoid sentencing, showing no remorse, etc., are evil actions. They indicate that he is evil.

His, and your, protestations to the contrary.
