Yes, if said attacks were against valid military targets and those civilian deaths were collateral damage. Consider the alternatives for Israel: 1) Send troops in without air support into hostile urban guerilla territory, resulting in heavy casualties, or 2) Do not retaliate for Oct 7, encouraging further future attacks and proving human shield tactics effective. From a game theory point of view, both of these are colossally stupid moves that would result in more Israeli deaths.

If you want to blame anyone for said civilian deaths, blame the terrorist government that provoked the attack while using them as human shields.
