The fundamental contradiction of the religious terrorist
By nature, the terrorist is the very definition of idol worshiper because, even as he/she espouses religious/ spiritual motives, his/her approach mistakes the physical being for its essence. Terrorism, is an act that, by destroying a building (ie. World Trade Center etc.) or murdering people, expresses a conviction that physical existence takes precedence over spiritual essence, and is therefore tantamount to a denial of God (hilul Hashem).
