How did the technological advancements in world war 1 change the moral compass of the world?

Fight beats the heart of a hero."

Explanation:

This statement has been characteristic throughout the centuries of human history. From the ancient period, the Middle Ages and the New Age until the beginning of the First World War. Since then, it no longer made sense to use it. The development of science and technology during the nineteenth century and from the early twentieth directly affected the military industry.

This resulted in innovations to be used for the first time in the war. Courage and strength have come to the fore, and technology has come to the fore. The use of poisons, tanks, flamethrowers altered people's moral compass. World War I was by this time, the most destructive conflict in human history. The extent of the destruction of the First World War caused the decline of moral values. Because after so many terrible devastations, humanity still did not learn a lesson in the perniciousness of the war and its meaninglessness. Thus, the First World War greatly impoverished moral values.
