Michael Shermer, in a short piece in Scientific American, coins the word "murdercide" for the actions of suicide bombers. He points out that suicide bombers aren't suicidal by the accepted definition of the word.
He also underscores the fact that "murderciders" (and it isn't a very compelling or elegant coinage, is it?) are usually well-educated, seemingly well-integrated members of society, a point which has often been made here. He recommends democracy for the Middle East as the best antidote.
