Romans 6:23 - Heretical Implications

I was handed this pamphlet today by a mysterious Hispanic woman at a S. Florida bus stop. Having read the Bible a number of times, I curiously decided to look it over. The page that stood out to me the most was the on on the left that reads. "For the wages of sin is death." (Romans 6:23). Now mind you, the Bible does say that, but it is referring to a metaphorical "spiritual death" in the afterlife, namely in Hell, or "the grave," which is comparable to the Greeks concept of "Hades." Anyhow, there are many nutty, wild-eyed, buffoonish, heretical, maniacal, and hopelessly ignorant zealots that believe that this very Bible verse advocates for, and justifies outright murder against people who "sin," namely against the God and Jesus of the Hebrew Bible, which is an extremely bad interpretation of the Bible.
