Abu Nidal

"One of the most effective GID chiefs was Gen. Saad Kheir, who headed the GID from 2000 to 2005. He excelled in penetrating extremist Palestinian groups, such as the Abu Nidal Organization, one of the deadliest in the 1970s and 80s, and later al-Qaida."

"People like Prabhakaran have been seen before in the blood splattered pages of history. The leaders of terrorist groups and ideological movements often display pathological behaviours, as do many of the great dictators like Mao, Stalin and Hitler. Abu Nidal, Abdullah Ocalan of the PKK, Jorge Briceno Suarez of FARC, and the Aum Shinrikyo leader Shoko Asahara all had histories that suggest psychopathic or sociopathic tendencies."
