I don't want to dismember my opponents.
I sure do love a katana!
But I find the ethics of Kenbudo are at odds with "my" Aikido. Like many people, I find something appealing about the spiritual facets of the budo ideal. But I practice Aikido because you don't really have to harm your opponent to defend yourself, unless you choose to, for whatever reason.
I'm finding that I'm getting more and more soft-hearted in my old age. Unless there are some very serious mitigating circumstances, I prefer not to have to kill anyone, or really even cause anyone any permanent injury.
OTOH, sometimes a weapon is called for, like in cases of multiple opponents, or when defending against "major" weaponry.
Who has similar reservations? What have you done to find a comfortable compromise between effectiveness and, shall we say "over-effectiveness"?
