They didn't deserve it
The death of Lily and James Potter was a horrible one. They were young, and they did not deserve to die. Luckily, though, Voldemort did not accomplish what he had set out to do. The boy lived.
Something had happened. Something that had prevented their son from dying. Dumbledore says it was love. Lily Potter loved her son so much that she sacrificed herself for him. I feel bad for the boy. He will grow up without a proper family, and he will have the weight of this on his shoulders.
The rumor is that Voldemort was vanquished. I, for one, do not believe it. He was simply weakened. He's out there, hiding. Someday a faithful servant will rejoin his master, and the Dark Lord will rise again. When he does, Harry Potter had better look out. We all should.
But, at the very end, it will all be okay. I don't know if I'll be alive to see it, but I certainly hope so. Good will triumph over evil, and light will shine down upon us all.
