@Lunarlors34Two reasons why he hasn't done that: 1) He doesn't want the other Shadow Heart members to bother him anymore, and second, he finds doing things this way entertaining as well. He wants to force them into a choice and see what they care more about, to see how true they really are to the 'Greater Good'. Remember, he likes to play with peoples minds as much as he wants to kill them. The scene in the Hotel room between the Shadow Heart members is a good example. He knows exactly how he can throw off Maxie's cool, because he has a very obvious and exploitable weakness.
