This is rather my thought on the matter. I am perhaps the most violence-avoiding person I know...until someone brings violence. At that point, I intend to end it. My attitude and approach to defense puts the lie to the notion that the term "aikido" must be about peace.
This reminds me of the black guy from the walking dead. he annoyed me so much with his silly attitude. he's so delusional.
he's in a war against zombies and violent people which murder and steal and he's like "but i dont want to kill people".
