In an ethical sense, virtue is the opposite of sin, that is, they are the good feelings or actions that can be carried out by a person that place them as "virtuous", a correct, strong and kind individual. This is one of the methods of religions to somehow create an individual who adapts to what their religion dictates, shaping their way of being and trying to change their thinking, making it one that does not include evil or some profane feeling.
In Greek culture it was given great importance, since the man who managed to perform great actions for his people, it was believed, was rewarded by the Gods with fortune and the best instruments, depending on the profession to which he dedicated himself. Proof of this is found in the legend of Hercules, who defeated an army much larger than his, so Zeus decided he would reward him with unique weapons and shields that they had.
