Lawful Good is probably the closest thing. It's always my strongest alignment, and it makes sense when I think about it. Preserving a sense of law and order is always my goal. Even in instances in which I bend/break the rules, I do so not secretly or for personal benefit, but openly, and to point out a flaw in the system so that the law/rule might be improved. Basically causing chaos with the express goal of imposing a new and improved order.
Even when I disagree with the law, I believe that a corrupt system is better than leaving things up to individuals. This is mainly because I believe that most people are too selfish, too stupid, or too morally bankrupt, and thus leaving things up to them, and thereby removing any semblance of government, would invariably lead to the destruction of all. I can not allow chaos to reign and will only circumvent law when there is simply no other way to accomplish a goal that I feel will be beneficial to society.
If a decision ever comes down to sticking by a friend or ensuring order, I unfortunately must always pick order. Dragon Age actually has a scenario that brings to light this conflict perfectly. Also, a job related conflict in which I had to fire my spouse for a rules violation comes to mind.
