Yes, it is Hanasaka Jiisann fairy tale.
Actually, I can not say for sure, which person is speaking.
All I have is sentences like below.
よくばりじいさんは こいぬを ころしてしまいました。
「なんと かわいそうなことを したもんじゃ。」
It could be good character regret about awful things done by bad character.
Or maybe it is bad charter lies. For example if he telling "Awful things were happened" to good character.
Thank you very much!
