Iran's strategy has been to use their proxy groups to force innocent civilians to be their human shields. Hamas has been thoroughly documented as using basic infrastructure such as hospitals as their command bases, prevent innocent civilians from fleeing war zones under the penalty of death, steal humanitarian aid to cause humanitarian crisis, and even infiltrating supposedly humanitarian organizations to abuse them to further their military and political goals.
Let's face the facts: the likes of Iran actively places civilians in arms way expecting it to be a win-win scenario, as in either it prevents any retaliation or leads people like you to misguide your indignation hoping to weaponize it.
There is a wealth of information on how Iran, through Hamas, is murdering palestinian civilians by playing them as expendable pawns. If you care about the problem then you'd be directing your indignation towards the root of the problem, and do your best to not create an upside to using civilians as sacrificial pawns.
