Three things: We aren’t giving weapons to Hamas to fight, they’re on the defence, and they’re a significantly less organized less advanced force. Gorilla warfare is the stand operating practice of a less advanced force fighting a more advanced one. They can’t hide in jungles though. They only have urban places (or directly next to the border).

Israel has the initiative. They get to choose when and how to take a fight (or to choose not to at all). Even when they put people in the area, they still commit atrocities, like dressing up as civilians and medical workers to assault a hospital and murdering civilians. I haven’t seen Hamas do such things.

I don’t think Hamas is good by any means. They just are. The situation in which they were created is not of their own will. The situation they fight in is not of their design. Their existence is also, in part, a piece of Israel’s desire and force. (They funneled money to them in order to create an enemy to fight against.) I don’t fault a lion for mistreatment of their prey, but I do fault humans for how we treat livestock. One does it because of the situation in which it lives, and the other does it out of a totally lack of respect, or potentially malice.
