Raydon had an insatiable greed for a life of unrestricted freedom, and in his previous life, the betrayals of those he held dear were what limited his pursuit of such freedom.
However, he was also unlucky in the sense that, as a member of the socially inclined human race, it was impossible for him to lead an entirely solitary life. As a result, he viewed the challenges he faced as a game in which he had to prevail in order to achieve his goals.
Therefore, in this new life, he had only one expectation from the people he had with him, and that was another reason why he continued to help Dan and the others.
Loyalty.
It was unacceptable for him to be in the company of a person who was not loyal to him.
