Oh, I get that he did. But the thing is, even when grandpas feel like telling very young children such traumatizing stories for whatever reason in their mind, they usually avoid all the killings and there would be a moral for the kids. Not praised for heroism. In that story, he goes against his dad's advice and wish, and is praised for it, he describe genocides, killings and a mutilated man to 6 years old kid as a bed time story.

I'm sorry if I'm a bit confused, but I'm just trying to justify and make sense of such attitude of a grand parent to tell young kids such pointless killings as a bedtime story.
