I will offer a reasoning why a lot of people do ethical violations, such extreme harm to others.
How I will try to explain these ethical violations is through the representation of “gun” imagery:
The “gun: ethical violations” is created by our biological such as ability of/for not to empathy.
The “bullets for this gun: ethical violations” are roughly created by our ability/limit to actualize ethical cognition.
The “trigger for this gun: ethical violations” pulled or not is roughly controlled by our management of emotional intelligence and/or our ability/limit to actualize Ethical/Moral Reasoning with a mixed framework of Rational AND Emotional thinking.
Where this “gun: ethical violations” is pointed seems to involve varied possibilities such as, situational, experiential, preferential, or is attitudinal.
