What do u think of this?

my friend martin (not giving any last names out) says his father is a douchebag! he says he hates his father for acting like an asshole for all these years. he has no love for his dad at all. he says that if he'll be happy if anything happend to his father, EVN IF HE DIED! thats horrible. so i tell him you shuld at least show some respect for him. and he said "HELL NO!". what do u think i shuld do
