Nope no way, there is no reason at all.
Anyone pointing to it promotes violence then that would mean action movies and thrillers and shows such as CSI should go too, which again i disagree with.
Horror movies are loved by some people just as romance and sci-fi......... it is what it is; a genre for entertainment, some people are entertained by explosions and fast cars, by jokes and shenanigans others by monsters and creatures.
