Surely most people can understand that if Israel was Great Britain and Hamas came and massacred children and innocent people in early October, then Great Britain would go to war and absolutely hammer them back? You just have to look at the response to any other war we’ve had. Do you really think the British government would behave perfectly in this situation? Do you think any western nation would do anything else in response to such an attack? I can genuinely see British people screaming in the streets to murder all babies of Hamas if this was the case. (Not saying it’s right!! I just don’t think we would be better in any way!!)
Personally I find this a really complicated conflict due to the deep history and I feel deeply sorry for civilians on each side.
