If you want to play semantics, going by deeds the IDF, and even the Israeli state, is a far more heinous terorist organisation than Hamas.
The Oct 7th attack was terrible, but the Israeli response (both the initial response when many Israelis were killed as well as the hell wrought unto Gaza) has been downright evil. And they way Israel whipped people up into a frenzy with sick fantasies about "40 beheaded babies", "babies on washing lines", mass rapes etc was utterly despicable.
