Reading his recent rants on Obama's (now reversed) plans to release more prisoner abuse photos and roll back illegal wiretapping and close Gitmo etc., we get the impression that behind Cheney's anger lies fear (I'm generously presuming that there actually is something more to old snarly face than pure primal anger). But what could provoke fear in man whose idea of private conflict resolution is to try and blow your face off with his shotgun?
While Dick is undoubtedly frustrated at the thought of an end to the vicarious pleasure he surely derives from his personal (if indirect) involvement in the waterboarding, sodomising or plain ol' beating to death of innocent people, not to mention an end to his personal assassination squad, the many degrees of separation between an order from the office of the VP and the "enhanced interrogation" room where the "fun" takes place ensure that Cheney need not fear any jail time for his "enhanced misdemeanors" (especially under the increasingly pusillanimous Obama aka "Judas Goat").
Like so many political debates of the last, say, 2000 years, the debate on the merits of torture in attempting to extract accurate information from an alleged suspect in the war on terror is hubris.
In 2002, the Bush administration was gearing up to launch an illegal invasion and occupation of Iraq for profit (and Israel). The CIA at that point was tasked with providing justification in the form of "evidence" that Saddam had links to "al-Qaeda." Under the direction of the office of the VP and the Sec of Defense, the CIA began torturing individuals whom they had picked up in random sweeps of Afghanistan and Pakistan (and later Iraq after the invasion).
To seasoned sadists like Cheney and high-level members of the CIA, it was clear that far from being a reliable way to extract accurate information from a prisoner, torture was much better suited to forcing a prisoner to state something that was not true -- prisoners like Ibn al-Shaykh al-Libi (who coincidentally appears to have been suicided recently in prison in Libya) and Abu Zubaydah who remains in Gitmo to this day.
al-Libi was reportedly tortured many times, including waterboarding, in Egypt and later in Libya. He was also locked in a 20-inch high "coffin" for 17 hours and then beaten for 15 minutes before he finally found sufficient inspiration and the "right answer" about those "links between Iraq and al-Qaeda."
