You have just distinguished between them. Why would someone react to an emotion if not to try to avoid it? When someone loses control in anger, it is not a pleasurable experience. Why would one do it? Only in hope that by expressing his anger, he would adjust the behavior of another person, so that they would stop making him so angry! Yes, it’s an insane logic, but this logic takes place in the unconscious, otherwise people would never say “sorry, I don’t know what came over me”.
