@Subliminal0,
It is not humanly possible, but you have to remember that a lot of times there are people around, using the term people as quasi, who have no conscience, and no emotional register at all; and that while some of these people become mass murderers there is the possibility that many such people never get on the radar as unusual in the least... People live and relate on an emotional level... It is out of their emotions and illogical desires and fears that reason comes to make possible their achievement of pleasure, or escape from pain...
Most of us can tell we are not inanimate by our emotions, and by connection with others, and with our sympathy and empathy we know others are alive as well... People without emotions are not people, but they are the walking dead, and missing the key part of their being which should remind them they are human and having a human connection, one that even allows them self pity and the awarness of the tragedy of life, and such people could end a life and take their own lives as easily as most people could shut off the lights, or turn of the engine in their cars... Such people may look normal, and dress and behave as others, and they may even have a sense of self as distinct from others, and yet, they are purely dangerous... Most of us have the means to balance emotion against reason, and unconsciously... To the extent people are unbalanced one way or the other, giving more weight to emotions or to reason -they are either useless, or dangerous... It is the single mindedness of the mass murderer that we should all fear, and the most terrible fact is that we expect those who hold great power to be detached in their reasoning from emotional considerations so that to hold office they would condemn thousands of their fellow citizens to war, or death... Behind such madness is always the irrationality of emotions, but when people are not forced to scrutinze their emotions with reason, and instead become the driving force and jusification for national and international mass murder, the act, the crime will be left in the hands of those best suited for the task: People without emotional connectedness...
The idea of forgiving people because they know not what they do is itself madness... Such people who do not know what they do, having neither consciousness or conscience because they do not have the emotional connection -are not human, and not capable of humanity and should themselves be destroyed or caged... Instead, we often elect them to office, or make them generals...
