Throughout history, various heretics (not to mention infidels, apostates and other non-believers in particular doctrines and dogmas) have been ostracized, persecuted, tortured and even killed for their particular beliefs (or lack thereof). Apparently we are often considered to be such a threat to the well being of society that if we are not eliminated we might actually be responsible for sending souls to everlasting perdition.
This fear, however, just goes to demonstrate the inconsistency in the theology of those who hold such a mindset. For those who believe in the idea of “free-will,” the individual is a free agent and completely responsible for whatever punishment one happens to bring upon oneself. This means that, while a “heretic” might reveal methods of bringing punishment upon oneself, the heretic can take none of the actual blame for the choice to believe whatever the heresy might be. Likewise, for those who believe in predestination, there is nothing a “heretic” could do that could change God’s election of one’s eternal destination. For a “heretic” to be at all responsible for somebody else going astray means that the heretic’s will is more powerful than the individual’s will or God’s will (depending on one’s stance on free-will vs. predestination).
This means that, even if everlasting torment in hell were true, us heretics should be considered to be no threat at all unless you believe us to be more powerful than both yourselves and God.
