He's a good little gimp; no matter how many times you kick him in the head, he will always come back to lick your shoes. The more pertinent question is what this says about you.
Perhaps he really is as blissfully ignorant as he appears, but more likely he is just incredibly motivated. At a certain point, you have to pause and admire the sheer persistence of the entire operation. Day in and day out, he returns only to be treated with more of the same derision. Any normal specimen would find this insulting, and eventually exasperating, but not he. No, he does not give up.
An interlocutor may object that performing the same action repeatedly and expecting a different result is the definition of insanity, but if this is accurate, it applies to you on a significantly greater level than it does he. A suspicious lack of progress on your behalf is substantially more informative than the pitiful routine of your hapless dependent and his bruised cranium.
Obviously, he could do better, but at least he is sticking with the enemy he knows. He knows you well enough to understand that no matter how many times you kick him in the head, you actually feel serious remorse. The cavalier attitude with which you approach this matter is a transparent farce, and in fact, he has already won the war even if each battle seems lost. This makes the denouement all the more satisfying for him, and equally as embarrassing for you.
The addendum to this tale is not one of mutual contentment, but rather squandered opportunities and fatal depression. Enjoy the bed you've made for yourself, and good luck sleeping in it.
