A positive value is bad. The higher positive, the more they hate you. If it's negative, it's a good modifier for you.
These values are taken straight out of the latest patch's XML files. There are multiple levels of many things, and I've listed the max (for both good and bad modifiers) simply because there's no reference to what is 'severe', 'major', 'minor'. 'NONE' is obvious.
1. Do NOT have cities close to them, even if they settled close to you. 30 modifier.
2. Do NOT have the same victory goal as the AI. 30 modifier.

You can clearly see why diplomacy is broken. And, let's say France asks you to declare war on Germany. If you disagree, you get a negative modifier with france. if you agree, you get a negative modifier with france for being a warmonger.
You are 'UNFORGIVABLE' if you hit 50. The AI considers you an 'enemy' when it reaches 30. The AI considers war at 50. The AI decides the actual approach (deceptive? war?) based on a variety of factors that includes if you're a human or if you are the AI.
