Is Torture open for Debate?

“It’s impossible to consider a violent Jesus: violence is contrary to God’s Kingdom, it’s an instrument of the Antichrist. Violence does not help humanity, it dehumanizes it.” – Pope Benedict XVI

CCC 2297 – Kidnapping and hostage taking bring on a reign of terror; by means of threats they subject their victims to intolerable pressures. They are morally wrong. Terrorism threatens, wounds, and kills indiscriminately; it is gravely against justice and charity. Torture which uses physical or moral violence to extract confessions, punish the guilty, frighten opponents, or satisfy hatred is contrary to respect for the person and for human dignity. Except when performed for strictly therapeutic medical reasons, directly intended amputations, mutilations, and sterilizations performed on innocent persons are against the moral law.

So I ask, can a Catholic candidate for public office openly support “torture” or “enhanced interrogation”?
