In many ways there is absence of 'passion' - it's a mercantile contract by the time of pressing the button: You do this / You get the virgins and your pic on local Tee Vee. Parents get the $25K.

Similarly.. a drug-induced euphoria may be more akin to the pre-button state (mentioned a few times by ex-wannabe bombers who fizzled). Passion however, requires that one is in possession of faculties (!) aware of the odds, afraid.. yet willing to act. *That* I believe is what we usually call 'bravery'.

Hell.. Every fanatic has that tired old courageofhisconvictions. Yawn
