similarities and differences

In this movie, Fantasy Island, the one thing that confuses me is that why would Paul Henley want to be hunted. Even though he lived, he still could have been killed many times. One other thing that confuses me if that Mr. Roarke wants him to be hunted and killed why did he save his life at the end of the last hunt.
One difference in The Most Dangerous Game is that Rainsford did not want to be hunted and Paul Henley did. One other difference is that Rainsford killed General Zaroff. In the story the main hunter saved the hunted. The last difference is that Paul only had to get to a red flag which was a certain distance away and rainsford had to survive for three days. A similarity between the two story lines is that both times the people that were being hunted won the hunt. Another similarity is that they were both hunters being hunted. The last similarity is that neither of them had a hunting weapon beside a knife.
