If I executed my technique without intent to cause harm, using my skills and abilities to deal with an unprovoked attack outside the dojo (where the attacker intended me harm), then any damage that occurred to the attacker as a consequence would be as a result of his own violence, not my Aikido.
Because violence means to do intentional harm. You can't be accidentally violent! At some level you have given yourself permission to deliberately attempt to inflict harm upon another human being if you choose to be violent.
I'm sorry but your staments seem to be contradictory. To say that the injury from your technique was the attacker's fault is akin to mining my fron lawn, and when one of my mines blows someone to bits saying "It wasn't MY fault, he was trespassing..." If you know a particular technique is capable of causing injury, and you intentionally use this technique, did you not intentionally put your attacker in a state potentially harmful? How is this not violence?
