Yes, Behn celebrates Wilmore. The primary way is that he isn't really punished. He's got all kinds of qualities that should qualify him as a villain, someone who the plot should work out badly for. However, he repeatedly succeeds in seducing women, including women who should know better. It is Belville who the soldiers seize, not Wilmore. An arrangement is made for him to marry the wealthy Hellena, a fate that essentially rewards him for his tomcatting around.
