Assuming they were kept hostage in Gaza, which was bombed by the IDF, chances are they were killed by their own people. Neither of them deserved to die, not the 100 Israelis, and not the THOUSANDS of Palestinians.
If the IDF hadn’t committed genocide, and these 100 were found dead after a few months, the Hamas could’ve entirely and rightfully been held accountable for their deaths. No questions asked!
But in this case, the IDF is even more to blame than the Hamas.
