Hatred is the only one-sided relationship in the game. It is possible for A to hate B, but B to not hate A. All other relationships are two-way. i.e., you cannot be at War with a realm that is not at War with you. But you *can* Hate a realm that does nto Hate you.
Once you have declared Hatred toward a realm, you can no longer change the relations from your side. The only way to get get out of Hatred is to let the *other* realm propose to change it. If *both* sides declare Hatred, then it can never be changed. Both realms are locked in Hatred for the rest of their existence.
Edit: Sorry for the tangent...
