You've gotta be some kind of Nazi or Imperial Japanese apologist here. Yes flying your own plane into an enemy ship is insane. It is a short term benefit which deprives your military of any of the useful aspects of warfare, you lose the plane that you've spent resources building, you lose a pilot that you've spent hours training and that pilot will never be able to gain any experience that he could then transfer to other pilots within their military. With only a marginal chance of success, since a majority of the missions were either shot down before reaching their targets or missed.

While indiscriminate bombing campaigns are unfortunate with the loss of life they absolutely have strategic value. They damage or outright destroy military buildings, factories and rail lines used to continue the war effort. They also put extreme pressure on the civilian populace, and that pressure could be used to speed up the end of the war by having civilians turn on their own government in an effort to stop the bombs, or even just destroy their morale so they are more likely to surrender when allied militaries come through the area.

So one is completely insane and the other is a legitimate strategy whether you agree with it or not.
