Okay, I get that I'm nine hours late to the conversation, but I've got to stand up in defense of ODD's alignment system:
(1) It's actually based in fiction, so people have more than just corebook+implications to draw on;
(2) Law and Chaos are external agents vying for the manner of reality, and the planes are just game-boards they've set up for their contests;
(3) Many races were created by one-or-other of the forces, leading to, yes, genetic ties to one side or the other. Not evil/good, but Law/Chaos;
