The love is a genre, we love what we desire. Charity in Greek is called Agape or love for the good, charity is the love perfected by the nature of good.  Love is a feeling, and the good is a nature. A nature is what the being tends towards his development, the fruit is good when it is mature, the house is good when it is finished. Every being tends towards his own good or perfection.
The love of Charity: "love your neighbor as yourself", Mark 12:31 is the love of the adult person, is the love of those who reach the conformity to God (be perfect, therefore, as your heaventy father is perfect, Matthew 5:48).
The paragraph in 1 Corinthians  13:4 describes the meaning of Charity;  Charity is patient, kind, is not proud, not dishonor others, no keeps records of wrongs. Charity is love without passions (passions push men to evil), is not selfish, is proyected to the others, is expansive,  is a mentality, is a form of benevolent intelligence towards the creation and our neighbor. Charity is the love of those full of the holy spirit, of those who have received the eternal life, the knowledge of God (John 17:3).
Charity is based on truth, progressivity, empathy.In the charitable man is observe a quality, the notion of the good, this notion is absent in the malevolence. What does this mean? That the idea of the good structures the thought, it articulates. In practical terms means not getting into the lives of others, not prejudice, be well prepared to solve problems that affect the common good, always seeking perfection and excellence. We could say that the opposite is Charity malevolence. Malevolence is prejudice, is selfish, see deception and evil on the others, and falsehood is its base. Good and evil are attitudes, ways of thinking.
