If you were granted one wish, what would it be for and why?

I wished the world to be a safer place, to have lesser floods and natural disasters and for all races to live together peacefully and harmoniously, no racial clashes and violence pervading the world.

I would wish that I could cure every illness. If I had a cure, the family members I have lost would still be with me now and I'd have comfort knowing I would'nt lose any more of the people I love. That goes for you too Allabarra Lantern, sorry for your loss.

I would wish that my son had been born strong, healthy and lived a long, happy fulfilling life instead of suffering a long, drawn-out, horrible, painful death from Cystic Fibrosis.

I wish to go back in time to save my friend that commited suicide, because saw that one coming. So i would wish to go back just to stop that. Even if it's worth my life
