What's the pathaway to justice for a family to go to die for the cause, when their children gonna die anyway if they do?
Vengeance has never been a pathway to justice, kamikazes go to die because their families are compensated or because their families are threatened or because they are radicalized in other ways, there's no connection between bombings and suicide bombers, in fact you don't see fathers or mothers do it, you see young males do it (85% of all suicide bombers are man).
Radical organizations use bombers as weapons, they need them to be reliable (as reliable as possible) you can't just count on the momentary lapse of reason that could bring a father to hope to kill his son's killers.
Hamas, for example, was against using women as suicide bombers, but in 2004 they changed idea, after the first woman was used, they said “this is a significant evolution in our fight. The male fighters face many obstacles... Women are like the reserve army―when there is a necessity, we use them.” [1]
