The IDF makes mistakes and fucks up. A big reason for many of the fuckups is the fact that Hamas combatants are not wearing uniforms and aren’t following the rules of war, and follow guerrilla tactics that are difficult to deal with for a conventional military.
For "exterminating entire families in their homes" we can hope that if such decisions were made without significant enough caution (a reason to believe that not bombing a building would cause more innocent people to die at some point and possibly lead to another attack similar to October 7, or to significant rocket attacks that could wipe out more families) it will be investigated and the decision makers will be punished. However, I don’t wish on anyone to be in the position to be evaluating such stakes.
Israel is a democracy with a functioning court. There is at least a remote chance for bringing justice. Here’s it’s probably important to mention, that unlike Israel that has high court that is actively fighting the Israeli politicians who break the law, Palestinians have pension schemes for families of the "martyrs" (let that sink in).
If you are this upset because of Hamas attack, imagine how Palestinians feel after years of bullying and abuses.
