That's exactly what.the Japanese wanted. They considered the soldiers who died in battle to the be the best soldiers, and that surrendering was the worst thing you could do. I imagine that's why there were so many Kamikaze pilots.
People die in wars, but if I was a leader in a war, I would try to get as much out of my troops as I could, so I would try to avoid intentionally sending them on one-way suicide missions unless that was the only way to get the job done. I would rather make do with the troops I have then try to recruit new ones.
