Suicide Bombers - How could you even contemplate Blowing yourself up ?

Have you ever wondered - what makes a person blow him/herself up along with a bus load of tourists ? Are they Mad ? Did Peter Powers hypnotise them ? Or were they just that glad to escape the life they had that they were only too pleased to kiss their azz goodbye ? Or was really because the Mutants behind it threaten to kill their family if they didnt ? Who Knows ? Was a memember of your family a stick of TNT ?
