What is the price of life?

Halliburton, a subcontracting company based in Texas, has received around $10 billion in money from the government for work done in Iraq. Although Halliburton is being audited and investigated for its business practices, Halliburton is still the prime contractor in Iraq. Halliburton has suffered 55 deaths at the hands of militants and other reasons since combat ended. Can this be defined as an externality? Is it fair for Halliburton to continue doing business in a without protection for its workers?
