AFO didn't kill you for some unknown reason...but he killed every single other family member you’d had. The war was a dreadful tragedy for you but so was it for many others. You’d started unfortunately finding your family members bodies after the massacre and you began to give them rightful burials.
They deserved that much at least..
When you found Kudo, he was obviously..strangled and beaten like an old street dog. It filled you with sorrow. He had no chance from the start...Although you couldn't blame him for the extinction of the whole family. So, You gave him a rightful burial as well, You buried him with everyone else in the family. Set his soul at rest or so you thought..Every single night after you buried Kudo’s body underneath the earth’s surface, you started seeing him in your dreams.
Kudo would just sit in complete silence, staring down at you firmly.
