No, they don't 'kills the people'. Your ignorance of reality should bring great disappointment to your parents. These soldiers kill only those who attempt to kill the innocent. Without these soldiers, girls would be forbidden from entering schools. If these girls were too old for schools, these soldiers help prevent them from being raped by the scum who these soldiers would like to educate with lead.
These animals in some of the countries are not treated in the same manner we treat them here. Many dog and cats are abused in these countries, just like the women.
Go visit one of these countries before you 'what the fuck' us again!
