You misread the parent comment as comparing the crimes, when in fact it was comparing the excuses for continuing to commit them, using a quote from a movie.
1. The comment to which you replied wasn't comparing violent war crimes to privacy violations, so your indignation was unnecessary.
2. Whether you're discussing war crimes, selling cancer-causing tobacco products, or spying on innocent civilians, the "just doing my job" and "I have a family and a mortgage" excuses are inadequate justification.
