The issue is not that Ben cannot control Rath - though I think this is a terrible way of putting it. Rath is not an independent being who acts of his volition but for Ben's control. He is Ben, only in the form of an Appoplexian. We know that Ben has, in the past, been unable to control his anger (for reference, this is particularly clear in Ken 10 and Secret of the Omnitrix). Rath just has a lot of anger.

Furthermore, by virtue of his being an Appoplexian, his consciousness is superimposed on the brain of an Appoplexian. It is more accurate to say that Ben's consciousness is compelled to perform actions that he otherwise would not by Rath's instincts.

The difference may be subtle, but consider it this way: when one is angry, one does not lose control. Rather, one is compelled by the anger to alter the reasoning process. In other words, Ben controls Rath, but always in his angriest state.

To take an example of an alien that Ben really could not control, consider the cases of Ghostfreak and Big Chill. Ghostfreak literally developed a foreign consciousness which actively sought to wrest control of the body. Big Chill did not assume a foreign conciousness per se, but his reproductive instincts also became a source of alternative willpower that assumed control of the body.
