Terrorists always repeat themselves with any act that doesn't end in total failure;
Before falling asleep last night, I thought, those kids without their families, parents, probably crying, who could do this, heck these terrorists are child molestors.
For a Terrorist, failure is not killing all of your hostages. This is what defines a terrorist and the realization that the people were not hostages, but victims when the terrorist chose to finish their planned attack.
