Is it normal to believe cyber criminals should pay the ultimate price?

OK, hold on just a second. I'm not talking about cyber criminals who might be seeking monetary gain, here. That's bad enough, but at least there is a point or purpose for the attacks.
I'm talking about those people who disseminate the viruses that cripple untold millions of computers, disrupt virtually the whole world's communication online and cost everybody from the biggest companies to each individual affected, billions and billions of dollars, just for their own amusement.
Jail is just too good for these malicious criminals. They gain absolutely nothing and everybody affected loses big time.
Perhaps if they knew that they would pay with their lives, they would find some other way to amuse themselves.
