Hamas does not want to wipe out every single Jew. From their 2017 charter:
Hamas affirms that its conflict is with the Zionist project not with the Jews because of their religion. Hamas does not wage a struggle against the Jews because they are Jewish but wages a struggle against the Zionists who occupy Palestine. Yet, it is the Zionists who constantly identify Judaism and the Jews with their own colonial project and illegal entity
And yes, I agree Israel won’t want to negotiate, because they have no interest in allowing Palestinians the right to self determination, which is what Hamas would be negotiating for.
