They assumed that if they set Italy and North Africa free they will reach the victory and defeat Japan, so this option is the only suitable.

The answer is:
~ It would ultimately ensure victory over Japanese forces.
One of the biggest allies of Germany was Italy, and defeating them ensured the ability to attack Germany from other fronts, by doing so, Japan would have less and less support from Germany and this will lead ultimately to its defeat.
