Regarding the motivation it is interesting to note that even some non-religious right-wing extremists have acknowledged that suicide bombings are quite efficent.
If your goal is to instigate fear in your opponent, what better way is there to show that you are ready to die for your cause?
About a year ago the swedish police arrested 3 neo-nazis not far from where I live. This group (just a few people, as far as I remember the police arrested three) was actually planning to recruit suicide bombers and use them in a terror campainng against the swedish society.
Now, I don't think they would have actually succeded in actually recruiting anyone (they were a bunch of losers, lots of planning and so on, but when they were arrested their "terror-campaign had been limited to smashing windows in the local school) but the point is that even in some western non-religous groups suicide bombers are considered good "tools" for whatever insane cause they are figthing for.
