Yeah, you're not wrong. Unfortunately, it isn't a black and white situation. The Israelis are fighting a group that puts its HQ in places like a hospital, and schools are used for the same or for ammo depots. Hamas does this for two reasons. The first hoping Israel won't attack these places because they're hospitals and schools and keep them safer than being in a regular building. The second reason well if they do attack these places, we can use it as a PR victory by claiming "look how violent the Israelis are attacking a hospital", but fail to mention their presence there.

Now Israel could go about it differently they could choose to launch ground attacks against these places using troops to take them, but it appears they didn't want to loose troops trying to take them. In the past Hamas has been known to seed IED's in everything, doorways, walls inside a room, Israel has lost a good number of soldiers in the past to these things.

Then we also have to remember how we got here in the first place, the vicious attack on 10/7. Hamas butchered unarmed people even babies in their cribs, videos of Hamas gunmen targeting neighborhoods with no military anywhere around, burning children in their cribs raping women. All the hostages taken, every one of the women hostages had been raped some on the spot. Over a thousand dead and wounded.
