What do you do with caught suicide bombers?

I have been wondering, what do you do with caught suicide bombers. But, I wonder how our courts would handle it. They never actually killed anyone, so they may not get the death sentence. But, I don't see how time in prison will make them want to blow themselves up and kill a bunch of normal civilians any less. I personally think being sentenced to death lets them be martyred...so they will be happy and the world will be safer.
