Every great martial art comes to the same conclusion at some time or another - violence is not the answer.  The difference between Aikido and other martial arts is that non-violence is something introduced in the beginning and not the end.  As Aikidoists, we understand that the person attacking us not in their right mind and as a result of is ignorant.  This lack of understanding or awareness is what brings them suffering because in the end they are only hurting themselves.  Knowing this, we try and use Aikido to resolve the conflict in a non-violent manner.  Kanazawa Sensei is a world renowned expert in Karate with 65 years of experience and has come to the same conclusion that violence is not the answer.  This video is the 2nd part  of four videos where Kanazawa Sensei talks about not only his history but his philosophies on life and Karate. https://www.youtube.com/watch?v=fgZcq9a1Z8o
