good post, although, in my opinion, the conscience is not implanted, there are some, sociopaths, whom do not have a conscience. It has a preordained , or vestige to make a conscience possible, if and when it is developed. What happened at Auchwitz and other places, to me, since evil has no bounds, is a result of the devil and his legions being able to ursurp the power of undeveloped consciences. ? word games, perhaps, but, to me, mercy is in the judgement of God, as to your statement of no mercy, but I know what you mean, emotions prevail over justice, but watchout, as emotions prevailed then, or rather through the written word of Langbehn and LeGarde, who convinced the northern German, the Volk, who were into New Age sort of religion anyway, their minds were led to believe certain things.
There are a few people, the Children Of Darkness, the sociopaths in whom it is missing or deficient. The Bible knew their kind and that's why it extorts evil-doers to be dealt with harshly. Its too bad we've gotten soft to the point that we're soliticious of murderers' tender psyches. No, my dear friend, if they are not put to death promptly, more innocent people will die. The only way to defeat evil is to destroy evil people wherever they exist.
