There is a point I think you are missing, and it's extremely clear to me. Most of beginners in other artial marts train with one main goal. Learn how to hurt people. When they join aikido they usually enter with the idea of "if I do a technique, and nage gets hurt, I am doing it the right way"
I trained karate, judo and taekwondo before I began with aikido. My "highest rank" was a 2nd kyu in karate, just a beginner. When I began in aikido I joined because I saw the chance to train "ultra techniques to break bones and crush heads with a few movements of my fingers". So, when I saw ikkyo the first time, I really thought the hidden idea was to break uke's elbow, and send him to the closer emergency hospital.
