Is the Japanese Manchuria Development Group a criminal organization in history?

My humble opinion: First, the composition of pioneer groups is complex, including agricultural immigrants and armed immigrants. Many of them are poor Japanese. Second, the poor peasants of Pioneer Group were trapped in the chariot by Japanese militarism. Besides, as far as the victims of Pioneer Group are concerned, most of them are old, weak, women and children. Third, founder county planted tombstones, not monuments. Tombstone is a basic right that any deceased person should enjoy, regardless of his status before his death. Fourth, in civilized countries, the maximum penalty should not exceed the death penalty. When a person dies, his sins will disappear with his body. Fifth, today there are not only cemeteries of allied soldiers such as the United States, Britain, France and Canada, but also cemeteries of German soldiers. They are also victims of war.
