In this situation immediate death and vaporization is the bets and least painfull way to go, as survivors suffer before dying a slow, painful death.

And due to their reckless acts, extinction will happen to the rest.

It's common with humans to want to be powerful, and when someone does, they get destroyed. They think that death and destruction is the best method

It is hell on earth. No man or woman is safe. This is what happens when someone gets too much power, they kill.

Extinction is garunteed for them. They all wish it could all go back, they could be happy. They miss the little things in life, that we often miss, or take for granted.
