Hamas is the elected government. If you want all followers of Hamas to “be dead” then you are referring to over half the population. Only a sadistic worshiper of death would suggest what you have said. By the way, the story of Hamas using people as shields is a fictitious one created by the Israeli government.
Of course they ARE cheering for death and suffering. It is the direct consequence of their bombing. Their violent, sadistic nature also came out when they threatened the reporter. Hamas is the elected government. It’s Israel’s responsibility to accept that and to deal with it - if Israel can at least pretend to be a civilized nation.
