You can use any kind of martial art to fill possible psychological or emotional gaps, but that has nothing to do with self-defense. In real situations, rituals and codes of honor are of no use to you. Your opponent comes to harm you and will attempt it in every deceitful way. He will never invite you to a fair fight; he will try to catch you off guard. You need an art that provides answers to every threat in any environment. Imagine trying to defend yourself with capoeira or Brazilian jiu-jitsu on a staircase.
