Reasons why dropping the atomic bomb on japan an inappropriate action

This action is disputed still, but some of the arguments against it include:

- a great number of people, mostly civilians died and killing people should be avoided. It is not clear if continued fighting would result in less deaths
- it gave a dangerous precedence of dropping atomic bombs on the civilian population, and this should be avoided ( so other countries, or the US should not try to think that it was effective and repeat it).
