Hamas's actions are nothing in comparison to the atrocities committed by the Israeli occupation forces over the past seven decades.
Palestine has been under constant betrayal, criminal oppression, and occupation, with its people living in abject poverty. They were forced to defend themselves against Israeli tanks using nothing but throwing rocks. If Hamas hadn't existed, there would be no Palestine left today.
If you bother to read genuine history, rather than falling for propaganda, you'll realize that Israel's claim of being the only democracy in the Middle East is a facade. Finding a non-Zionist Israeli citizen is like finding a needle in a haystack. According to B'Tselem, a renowned Israeli human rights organization, the Israeli government has systematically deprived Palestinians of their basic rights, subjecting them to a cruel and inhumane occupation. So, next time you hear about "terrorism" in the region, remember who the real aggressor is.
