Torture: Immoral, Illegal, and...

The lawsuit, which the ACLU said it would file Wednesday in the U.S. District Court for the Northern District of California, charges that Jeppesen knowingly provided direct flight services to the CIA that enabled the clandestine transportation of the men to secret overseas locations, where they were tortured and subjected to other "forms of cruel, inhuman and degrading treatment" under the agency's "extraordinary rendition" program.

Ineffective...

Apparently, evoking the Gestapo is not an effective interrogation method:

As the Bush administration completes secret new rules governing interrogations, a group of experts advising the intelligence agencies are arguing that the harsh techniques used since the 2001 terrorist attacks are outmoded, amateurish and unreliable.

Illegal, immoral, ineffective. Why do it? Revenge? Sadism?

Exactly. And only a Sith Lord seeks revenge.
