William is too proud of who he is to even consider the thought of changing. In the movie he brags about killing his brother. "This is just too perfect! First I killed your brother. Now I kill you-" Before you say it's just the movie, than try to explain the books as well. Scott scrapped 7-9 scripts of the movie. If William's personality didn't fit the script he would have scrapped this one as well
@@KaiserLucian1608 Yeah, there's no doubt in that (i'm not being sarcastic). He is the plot device that's pulling all the strings. But that doesn't mean he's a force that should be seen as a joke. William is a bloodthirsty physcho who would do anything inorder to get what he wants.
