Background
Accidental Rebel: Due to the fact that Ferret is a selfish son of a bitch, and does everything for the sheer benefit of himself, he's made an enemy of almost everyone on each planet he visited. Along the lines he found himself in a serious predicament where he literally stole one of the slave women from an evil tyrant who has power over an entire galaxy. Ferret may or may not have had his way with this slave, but that's part of his mystery. The point still stands that he's performed indecent and selfish acts for his own reasons, whether or not they were the right decisions to make is yet to be decided, but that alone has caused him to make a very powerful foe.
Motivation
The Underworld: Every act performed is an act of selfishness, and if by chance it appears not to be, a selfish reason will always exist, whether just to keep up an image or to be in actuality selfish. This path has led Ferret to make enemies of everyone in his path, whether it be from the swindling of exotic goods, services or even women, or even simply from miscommunication. Regardless of the situation, he's always in the wrong place at the wrong time, and always looks out for number one.
