The control group is usually the group in which none of their variables are changed. This group is used in order to compare it with the outcomes of the other groups.
When ignore a conflict : you make the conflict become deeper and deeper that could lead to vengeful feeling between you and that other person
When you confront a person : you may hurt that person's feeling during the confrontation and that both of you and that person could explode in uncontrollable rage
When mediate a conflict : one of the party may think that you took the other's side, which also could lead to uncontrollable anger
