You are asking the wrong question. The question is "what are they losing from this" and the answer is nothing. They have committed war crimes for decades and not only is nobody turning away from them instead they get pumped full of even more and better weapons. Look at all the aid the west (mainly US) is sending them.
Why would they ever think about potential consequences if there are never any?
The fact that we have had around 100 or more articles about Hamas and attacks from Hamas members in the last few days says your question is somewhat superficial.
Everyone seems to agree that it is news. There's plenty of articles about individuals claiming to be for Palestine that make very questionable statements.
You know what the big difference here is though?
Israel has very broad support in the rest of the world. Especially the west. The most powerful economies on the planet. Who send Israel tons of aid. The US just parked an aircraft carrier strike group in their front yard.
Both sides have fanatics stating how they want to eradicate the other. Only one said has absolute control over the other though and has the means to actually follow through with their plans.
