"We Need to Talk About Kevin" is a harrowing look at the nurturing of a burgeoning psychopath, but it just seems like there's an edge missing.

Arrows and caustic fluids are scary, but they pale in comparison to Christmas ornament booby traps that set your head on fire. For real mayhem, there is only one young master: "Home Alone"'s Kevin McAllister.

Fortunately, one video mashup has solved everyone's problems by bringing the two parties together into one hilariously terrifying trailer. It's "We Need to Talk About Kevin McAllister," and it will have you reevaluating just what was so cute about a kid torturing grown men on Christmas.

Sweet little boy, indeed.
