It's much more realistic when in a roleplaying game a person doesn't automatically know good from evil, or if someone is dangerous just because of their race. In real life good and evil aren't so clear, and debatably only a human concept with no objective existance. It sounds to me like this new world allows for a lot more moral conflict, because from what you are saying I get the impression people have to rely much more on their own judgment, rather than simply some ability to sense good or evil, or judgment by the person's race, as to what's good and what's not, and what is or isn't a threat. What if you end up misjudging someone as good or evil when they really aren't what they seem? The threat of that certainly is very real, and while that threat was was in D&D with the right spells it was much easier to tell who was a threat and who wasn't, making it harder for evil people to be manipulative and seem like something other than they are (and evil that doesn't seem like evil can be very scary).
Is there no racism is Eberon (I haven't read much about it so I don't know)? Because really if there is I can imagine humans would be very racist towards certain beings such as kobolds (and vice versa) and the two could very well simply assume the other is hostile regardless of the reality and attack each other just because of that. Unless this is a world free of prejudice as well I can imagine there would still be a lot of strife due to just that, just like in real life.
