Except only one of those organizations killed 30 000 civilians within 7 months.
That's why you see reports of 600 extended families being completely erased, just because they lived together. It's not random civilians here and there.
Or do you see this as some just warfare on Israel part? https://www.972mag.com/lavender-ai-israeli-army-gaza/
And I think Israel should not wage its extermination campaign at all, btw. So I simply don't agree with the premise of your question, personally.
Unless you're trying to claim that Israel has decimated 75% of Hamas, and is almost done, let's not try to diminish this.
The number has also been largely substantiated by press and aid agencies, it's not just Gazan propaganda.
