Probably not. However if Grandpa’s Pride and Joy had killed everyone in the house and then went and murdered 10 or 15 other innocents, Grandpa would be as happy as a cow in clover. Because in Grandpa’s point of view, whatever his Pride and Joy desires, he should get it. No one, again, in Grandpa’s point of view should tell him nay. Grandpa’s pos got exactly what he deserved. My empathy and sympathy is with the guy who had to kill him to save his own life.
Whaaa, it wasn’t faaaaair! Grandpa should “live the rest of his life” with the guilt he didn’t raise the little punk by the Good Book. A few lessons in “Thou shalt not steal” would have him alive today.
