What if we can control who dies with a mobile device? Would you use it for good or for evil? Would you kill those who diss you in the early morning?
Let's say you stumble upon that so called phone. Literally a killer device. All you need is just the other party phone number, the number is untraceable and all you gotta do is either say die or say how, when and where. But here is the catch. That person doesn't die. Instead somebody of blood relation dies in his place. Everytime you call, the id shown on that person phone is the one that is gonna die.
Only when all members of his blood relation has die, only then it's his turn. After one complete cycle, you will lose ownership of the phone. When that happens, what will you do? Who can you trust? Seclude yourself from a life without any mobile device? Sure if it's easy living without one in this age. How do you know if it is really your mom whose on the other line? What if it's an emergency?
An example will be, supposedly that somebody of your family was warded and is currently in the A&E and they require any family member to be there to do some admin matters. Just so happen that everybody else is not free. Halfway while you're writing the particulars it states your name and time of death and such. How will you react? Freak out and clarify if the hospital made a mistake?
Go ahead, it'll only make you look like a lunatic. Sooner or later you might want to take your own life to end the madness.
