Disappointing ending

I am upset with the ending. The whole time I was rooting for his revenge which was fun but the old man did not receive what I wanted for him, instead we just felt pity for him. I wanted to be happy watching him be punished. I respect the writers for showing a diff side of the old man but c'mon the whole plot was revenge!! For that reason, I rate the show 8/10. I have truly loved watching this show every weekend <3 It has been one of my favourite parts of my week, but again that ending was disappointing
