Scientists learn to erase the fear of the human mind

We've all read stories ever style 'John without fear' or, in the world of comics, superheroes like Daredevil, a fictional character whose main weapon is their lack of sense of fear.

Indeed, one could argue that fear is good, because thanks to him we know that should not be approached in a reckless manner on the edge of a cliff on a windy day. However, scientists diabolical not seem to agree with this idea and are developing a special technique that would be able to eliminate that feeling fearful mind.
The idea of this technique, researchers from the University of Uppala , Sweden, and is based on the functioning of the human brain itself and how memories are fixed in the mind.
According to these scientists, your mind does not remember events that occurred before literally, instead what is fixed in the memory is the last time that you thought about it.
Therefore, if you delete the consolidation process that occurs after a traumatic event, which is fixed in your mind is a memory that is not associated with any feeling.
The idea behind this invention is to avoid negative feelings and emotions that are fixed in the mind after someone has suffered an accident or theft, to name a few examples. Other potential 'Utilities' (with quotes) would get a battalion of soldiers was a reckless battle.
However, it could be said that basically is just another step designed to dehumanize the human mind, especially if the method also works to eliminate or positive emotions, coming to an end, any kind of emotion. Disturbing.
