Kid, civilians die in war zones, that's sad truth about world that you was born into. It sucks that this child was killed. Nobody in IDF or in any other army wants to kill civilians and children, btw unlike Hamas pigs that openly bragged about it, and benefit from every single civilian death in this conflict.

> Why

Because there's no shortage of armchair operators that know better how to make split second decisions in combat. Also, they never do anything wrong because they never happen to be in situation where you have to decide between bad and worse.
