"unlucky civilians are fair game" that's been an unfortunate fact of war since, well, war was invented. maybe you should more angry at the people who started the war and put people in harms way, instead of complaining that one of the most precise operations still had unintended civilian consequences.
taking the moral high ground is easy when you are not the one making decisions, and while the lesser of two evils (in your car bomb example) doesn't make sense on a personal level, it does make sense on a macro level
