Yes. Israel is defending themselves against Hamas terrorists, they don't fight for fun. "It is true we have won all our wars, but we have paid for them. We don't want victories anymore." - Golda Meir.
What on Earth would lead you to think Hamas cares about Gaza residents? The whole point of Hamas's attacks was to provoke this sort of Israeli reaction. The innocent Palestinians who are going to die in this attack are no more than disposable pawns and human shields to Hamas.
