I think that most people on earth are good people, still. Most of them are not invading countries and hurting others, they are just trying to live their lifes and help others. Some of the people that commited the horrible acts are misguided or have been hurt themselves to the point of madness. Which does not make it okay. Far from it. They are dangerous and should be stopped. But it also does not make them purely evil.
No human should be viewed as an animal, even if they have done the most atrocious things, which Hamas has. This is not to reduce or deny the severity of what they and the Russian government has done or to deny the suffering they have caused. Not at all.
But they are the ones viewing other as less than human, as animals. This is what makes them able to hurt others like this. And while it is very understandable that our own pain and empathy with those that are hurt makes us want to view them as animals, so we can hurt them back, I do not think it is the way to go. I think it is far more powerful to stop them while keeping our humanity. The more we do that, the more we show that we cannot be broken by them, no matter what they do.
