In ww2 what were the consequences of killing civilians to shorten the war

The World War II was sucessfully ended by the Alliances launching systematic air strikes on German cities and as a consequence, killing more than 400,000 German civilians.

Explanation:

Royal Air Force and the US-Air Force were systematically air raiding cities, town and villages in Germany, from mid 1945 till German Nazi capitulation and end of the war in 1945.

This strategic bombing campaign did have devastating effect on the German civil population who were mostly victims.

As example, Dresden (East Germany) lost more than 20,000 civilians only in first two weeks of February, 1945.
