Greater good – fear of prosecution problematic  Sometimes people will do bad things in order to achieve good and necessary results. For example, the Allied bombing campaigns in the Second World War would be highly likely to amount to a war crime under the Rome Statute if they were done today. They were indiscriminate, they targeted civilians, and additionally even at the time were recognised as having little military value. Instead the idea was to terrorise the civilian population. [1] Yet they were considered to be necessary as showing the allies were doing something to aid the Soviet Union. The same might be the case with the dropping of the atomic bomb on Hiroshima and Nagasaki, they clearly targeted civilians, yet if they helped end the war without a ground invasion of Japan then this war crime might have been for the greater good. [2]  Head of state immunity allows individuals to take unpopular and difficult decisions that are necessary for a greater good in government without fear of prosecution for their actions. We need our leaders to be able to take decisions based on the national interest, not based upon their concern for their life after office.
