Ned's execution and Jaime's hand certainly spring to mind. But these are obvious choices.
The Rat Cook was chilling. Would have made a good Stephen King story. Too bad the series couldn't milk it for its true value.
However, I'm going to go with ASOIAF's very first chapter, where Ser Waymar Royce is slaughtered by the White Walkers. Impeccable writing suffused with the feeling of dread from an unknowable, pervasive and inescapable mortal threat. It set a perfect backdrop for the entire saga, growing from a single horrific incident into a symbolic representation of humanity's helplessness and ultimate fate.
