In regards to violence on the mat, completely unacceptable. Causing deliberate harm to your uke is irresponsible. It is your responsiblity as Nage to protect you uke through out the technique. There is no grey area, plain black and white. There is a high level of trust in Aikido practice, of which responsibilty to your uke is paramount. Anyone who trains in such a manner is a liability to the dojo and shouldnt be taught in Budo of any manner.
I believe O Sensei often caused pain, and sometimes broke bones.
From what I have heard, seen and experienced, it still occurs at the highest level of aikido.
