Of course it’s always difficult counting the dead, and Russia doesn’t allow any monitoring of this kind of thing in the territory it controls. But it’s likely the number of civilian deaths is around double that of Gaza. The numbers for the military is likely more than double that.

Ukraine does it’s best to protect it’s civilian population and their soldiers wear uniforms. Hamas does not wear uniforms, and actively prevents civilians from evacuating from areas where there’s combat operations. In fact having combat operations happening in populated areas was basically the point of massacring villages while taking hostages, both of which are war crimes. If you want to negotiate a prisoner release you don’t massacre villages, if you want a war that minimizes civilian casualties, you don’t take hostages to densely populated areas.

Hamas created a scenario to maximize civilian deaths, and it will probably never be known the true number of civilian deaths since they didn’t wear uniforms so the number of Hamas dead and number of civilian deaths can’t be distinguished. Israel claims half the number you see reported are Hamas, while Hamas claims it’s much less.

Note the difference between a military that protects it’s civilians and wears uniforms and what Hamas is doing. Larger numbers of soldiers than civilians die in Ukraine because they prioritize protecting civilians, while larger numbers of civilians than soldiers die in Gaza as fodder for their propaganda machine.

Note that Hamas is suddenly wearing uniforms as soon as a ceasefire is in effect. How often do you remember seeing them wear uniforms in combat when doing so would prevent civilian casualties? They have uniforms, they just don’t wear them in combat in order to maximize confusion which results in civilian casualties.
