Israel are a nuclear power, probably one of the most powerful countries in the middle east at this point. They don't need help protecting themselves when they just use Hamas as an excuse to oppress the Palestinian populace. Hamas is a terrorist organisation, Israel has a multifaceted military.

Honestly, it probably benefits Israel to keep Hamas around, it's the excuse and justification for their actions. Get rid of Hamas and it becomes harder to justify their abuse and violence of and towards the palestinian people. With Hamas though, they can keep the support of ignorant masses who think that human rights abuse is okay because brown person = terrorist.
