Man, I don't know how I could stomach that guilt. Knowing that your rescue came at the cost of many more innocent civilians killed and wounded, including children. I don't think I'd be able to look at any of the victims who survived in the face, let alone grieving family.
What's really twisted is it isn't the hostages' faults either that all those people died. I don't know if I'd even blame the kidnappers for those deaths. Surely the IDF could've done more to prevent civilian deaths.
It would take a monstrous person to not feel considerable guilt after this. I guess we'll find out the type of person these hostages are.
