Also remember that you can have a True Neutral character that believes in things like truth and love and altruism and fluffy bunnies so long as he's willing to murder, lie, torture, and decapitate kittens to achieve them.
Depends on the DM- some will enforce rapid slide to Evil if the character is routinely committing very evil acts, even if the neutral character retains "belief in love and altruism".
