and rarely do the two go unpaired in any soul. Sadly there is a less than complete understanding of what constitutes a vice and what a virtue. Thus do most common folk do their best to practice their virtues and shun their vices. Virtues and vices can be invoked, yet the results are rarely, if ever, predictable.
Not even Angels, as Old Scratch himself proved. For what can one control if not themselves? And yet none are perfect. Virtue and Vice, the amalgam of what makes each mortal and even many of the immortals who and what they are, are often seen as at once the most controllable of all the Powers and the most dangerous. It is a Vice, and I have enough of those failings that I prefer not to court disaster by adding another.
