From Law 3: Conceal Your Intentions

REVERSAL

No smoke screen, red herring, false sincerity, or any other diversionary device will succeed in concealing your intentions if you already have an established reputation for deception. And as you get older and achieve success, it often becomes increasingly difficult to disguise your cunning. Everyone knows you practice deception; persist in playing naive and you run the risk of seeming the rankest hypocrite, which will severely limit your room for manoeuvre. In such cases, it is better to own up, to appear the honest rogue, or better, the repentant rogue. Not only will you be admired for your frankness, but, most wonderful and strange of all, you will be able to continue your stratagems.

If I'm honest about my deception and show remorse, why will I be able to continue my stratagems? Wouldn't that look bad to continue after being regretful?
