How to deal with anger issues.

You are leading a group for adults who have anger issues. The group is comprised of 12 males, ages 25-45. One group member, in particular, has been extremely difficult and confrontational towards other members. Two group members have spoken to you after the last group session to share that they will no longer continue to participate if the difficult group member is not terminated. How would you handle that situation? Would you consider terminating the difficult group member, why or why not? Use chapter 9 as one of your sources.
