If Israel wanted to maximize casualties, there would not be a Palestinian alive today. What would be their incentive to stop? The far left claims it’s a genocide as it is. What would actually killing them all be, then? Double genocide? You have used the worst term you can to describe something very far from the worst Israel could do.
And then of course, is the obvious contradiction that they just agreed to a ceasefire for their hostages. Just like they did in November 2023. And how they agreed to a ceasefire in Lebanon despite all the cries of them trying to seize the land. Israel wants to be left alone to live; the Palestinians (and the other neighboring Arab nations) want to kill all the Israelis and destroy Israel. The rest of the world wants these positions to meet in the middle, so there we are in the middle ground: perpetual war. Go look at the Hamas and Hezbollah founding charters, or the Houthi flag, or everything Iran says.
