The Viet Cong killed hundreds in the same way, and so have all successful revolutionary groups in the past. Decolonization is violent, if you don’t like it don’t colonize in the first place.
Edit: And Hamas, even with their far less precise gear and without military superiority, has done a far better job avoiding killing civilians than the occupation has. The final death toll from the Oct 7 retaliation is now thought to be 695 Israeli “civilians” (mostly unarmed IDF conscripts), 373 armed IDF members, 71 foreigners and 36 children. While Israel has killed over 30 thousand Palestinians, 2/3 of whom are women and children.
