I think that is part of what makes interesting moments in playing alignments. Esentially, your character has to choose which as more value to him. There's no one side that is inherently more influential than the other, that's a judgement that you make about your character's frame of mind and helps you decide how your character reacts.

Here's why: a Lawful Good person believes that law is important to promote "good" things (life, liberty, happiness, opportunity). If the law is not operating in the service of good (aka if it is allowing slavery), the law is being abused and must be denounced. Now, a Lawful Neutral character will probably go along with and participate in the slavery as long as it does not blatantly encourage "evil" things like severe physical abuse, rape, etc. To that character, the law is most important and must be respected, but they will remove themselves from the situation if the laws seem unsettling to them. A Lawful Evil character believes that the law exists to be manipulated for the greatest personal benefit regardless of how it affects others. Such a character will freely and openly participate in a society that allows slavery if that serves his purposes.
Just some thoughts...
