Will a tazer kill me?

I recently bought the Weishi 669 series self-defensive flashlight, http://www.wildbillwholesale.com/800kstungun.html, and I was wondering if this will kill someone? I don't want to be a murderer. Where on the body is the safest place to be tazed? It says the output pulse voltage is 800KV and the current consumption is <1.9A(for electric shock) and <0.8A(for illumination)
