But does aikido teach that technique for offensive purposes? Or for life and death situations only where this technique is used as a last resort to save an innocent life against a malicious person? If it`s taught purely for self defence and that is made clear in the training, then it is not violent, in my opinion. But if it`s taught with ambiguity where just the technique is taught and one understands this technique can kill but no one is told the responsibility they have in knowing this technique nor any clear indications are given that this is a technique used ONLY for extreme self defence situations, then that is dangerous and I would conclude either the belts need to stop before one reaches this point of training or the whole martial art of aikido is corrupt in its core if that is what it ultimately leads to. However, even though I have no experinece with aikido and have never looked at it more than on the surface, it has been explained to me that the core of aikido is purely self defense. I hope that is true. Of course, anyone can take the training and turn it into something bad. All good can be used for corrupt purposes so to answer if aikido is good or bad lies in its own teaching. If its goal is to take innocent people thinking they are entering a peaceful, self defense art, get them really deep into it and then show its ultimate goal of how to kill then that is very wicked. It`s a very cultish tactic. I `d prefer the martial art that shows upfront that it`s all about teaching a person to fight and to be cocky about it. At least the latter tells the truth from the start and people can go into it making the known, wicked choice. There`s no deception. Anyway, I hope aikido is not like that.
