Given Hamas' explicit genocidal goals, I think we can expect some portion of their strikes will simply aim to maximize Jewish deaths, even as others may target specific military assets.
See for example Russia's recent Hroza strike (https://en.wikipedia.org/wiki/Hroza_missile_attack), which killed 59 at a memorial service. Hamas can't really do strikes like that today; they would just miss with overwhelming probability. I think that will change soon if they remain in power.
The Iskander missile has a 1500lb warhead. Compare the number of deaths it causes to the number of deaths a single unguided Israeli bomb causes in Gaza when it hits a populated building, and you will soon realize that the guidance is not the determining factor here, it's just the mass of explosives.
Because people left. Of course, if you bomb an empty building few will die. We're not looking at averages here, we're looking at single incidents that caused many deaths.
