And don't you find that just a little cruel? A tad dramatic? A touch..nasty?...
Ah well. Granted. Twice.
1, No corruption needed with this wish, it's corrupt enough already.
2, Just in case you need me to corrupt it, fine. Every life form on every planet within around 4.6 billion light years instantly suffers a cataclysmic and horrifying death. Except you. The incredible cosmic event that caused all this death and destruction, lets call it 'armageddon', somehow leaves you alive. More than merely alive, in fact. You are transformed into a being that is truly immortal. Not just long lived, but something that cannot die, no matter what. You now have eternity alone to think about the consequences of your wish. No beings that were outside the area of effect will ever contact you, because it would take a minimum of 4.6 billion years for any signal to reach you, and why try sending anything into an area that huge that is completely dead. So you remain, lonely, watching the universe slowly expand and cool in heat-death. Enjoy.
I wish for something nice.
