Mine varies pretty wildly from character to character. I have a tendency to make their morality loosen the higher their Magic or the lower their Essence, though; with great extremes of power comes a sort of "inhumanity," whether that increase in ability is coming from losing parts of yourself to technology, or being able to perform wildly superhuman feats from magical power.
Coincidentally, of course, the lower your Essence and the higher your Magic, for the most part, the farther in a campaign things are going; so the morals have a tendency to be slipping anyways, as a long-lived criminal gets dirtier and dirtier just from the nature of the business.
