Abdul-Rahman Kassig, also known to us as Peter, was a young American who personified the values of altruism and compassion which are the very essence of his adopted religion of Islam. This was a young man who traveled to one of the world's most dangerous places to care for the innocent victims of a bloody conflict, and fearlessly dedicated himself to helping those in need. There can be no greater contrast than that between Abdul-Rahman’s generosity of spirit and the pernicious evil of ISIL.

During his time in captivity, his family, and the entire government, including his home state Senator Joe Donnelly, worked to avoid this tragic outcome. His mother's searing plea directed to his captors is unforgettable. The fact that her appeal went unheeded is only further testament to the wicked inhumanity of the ISIL terrorists who have taken her son from her. Just as we witnessed with Jim Foley and Steven Sotloff, the sincere efforts of so many to bring home innocent hostages have been met with blood and barbarity.

On a day like this, even as we reiterate that the United States and the civilized world will defeat those who have killed so many innocents, we can all find inspiration in the commitment of Ed and Paula Kassig. Their devotion to their son is remarkable. They never stopped trying to bring him home. They never gave up. The Kassigs raised a young man who was courageous and selfless to the core, and after seeing the way his family fought on his behalf, it is clear those virtues define the entire family that loved him so much.
