The voltage itself doesn't do anything, it's the electric current that a high voltage can produce what kills you. A high current can disipate a lot of energy in your body (human body has low conductivity), and literally burns you.

Yes but you will probably die of a heart attack, not burns, because the current disrupts the regulatory electrical impulses in your heart. See Wikipedia. – Mark Mitchison Jan 16 at 21:50
