Actually, my own grandfather died yesterday (yeah, really). In the end he was very sick; he tried to come back to the house and be taken care of; we literally dragged him into the street, like a dog...
He was a true rapist incestuous pedophile piece of shit who died painfully but still managed to fuck our lives to the very end, by splitting the friendship between my mother and her sisters. My mom and I were the only one who didn't go to his death bed, ever forgive him or said goodbye to him... and at least I do not regret any of it. I was relieved that, at least, that worthless scumbag is finally gone.
