"You'll never know what hit you"

It would seem that you've made an grave error this time around. You stand over the half dead body of what looked like a feeble old woman. It was just a moment of a power trip, just wanting to get the thrill of a kill once again. Or perhaps it wasn't as clear cut as that, but whatever the reasoning, your actions caused the death of the woman by your feet. You were going to walk away when the old woman grabbed your leg with strength that shouldn't even be possible.

You look down at the elderly woman, to see a hateful scorning look in her eyes, more than you've ever seen. She spoke one last sentence.

"Curse you.. you've taken my life, but I swear on my dying breath that yours will be nothing but tragedy. You and the one you love will face a life of suffering and torment as payment for taking my life prematurely."

With that, the old lady died, leaving you confused, perhaps a bit scared, you quickly left, not knowing what you have caused for yourself.

What do you do?
