Watch "The Omen II" then, it's a much better movie in most ways since Damian is the protagonist in his own right and can hold a conversation. It actually gives Damian a human dimension, and suggests that, since he's incarnate, there's a human element to him, which makes some of his choices hard for him.

The scene where he begs his adopted brother to stand by his side when he comes into his power and his reaction when his brother rejects him, is a very effective moment.
