Brutal as far as I know it, and no I am not one who reads and sleeps with a dictionary but" force with the intension to harm ,animal like" is what I think it may mean. Literally, but I am simply stateing my opinion on it.For purpose of discussion. I like to hear what other have to say on it. I also agree that someone could make their aikido "brutal" but that is not true aikido. It is a form of aikido. Lets not argue that.
