Remember that the alignments as they're spelled out are only guidelines for your character's RP - so long as you stick to those guidelines you should be alright.
For example -
Code:
help scrupulous
Scrupulous characters value life, freedom, and happiness above all else,
but find the traditional methods with achieving these goals to be cumbersome.
They have the best of intentions, but are sometimes ruthless and lack the
necessary caution, occasionally hurting innocents in the process. They are
willing to work with anyone who will help them in their cause, and usually
make incredible leaders. They lack the discipline necessary to be effective
long-term rulers, becoming frustrated by all the red tape needed to run an
organized society.

Now pulling this apart, we see that Scrupulous characters, despite their white aura, can be ruthless and carefree, and even hurt people to further their goals, possibly breaking laws in the process. Now what this means tends to be in the realm of 'do what you think is right'. So what is it your character thinks is right?
I'll give you all a clue to my current character when I say that he's scrupulous and is currently having just this sort of interior debate - if you've met him you know what I'm talking about
