Question about Enkidu

I’m puzzled. In the beginning of Enkidu’s flashback, it’s suggested that Enkidu is free, in the sense that he’s not controlled by Traumerei. But then, we learn that Traumerai is capable of controlling humans, and that he controlled Enkidu to kill Amizu.

Does this entail that, in fact, Enkidu was manipulated/brainwashed by Traumerei all along? And that his relationship with Enkidu reflects the fact that Traumerei can only bond with people he can control or dominate?
