Why should Man be loved?

Why Man Should Be Loved - You ask me,  Why should Man be loved??
I answer: the reason for loving Man is Man himself. And why should Man be loved for his own sake? Simply because Man is created to reflect the majesty and love of God. 
The First Degree of Love: Love of Self for Self's Sake
Love is a natural human affection. It comes from God. Hence the first and greatest commandment is, "Thou shalt love the Lord thy God." But human nature is weak and therefore compelled to love itself and serve itself first. In the human realm people love themselves for their own sake. This is planted within us for who ever hated his own self?
The Second Degree of Love: Love of  Others for Self's Sake 
I cannot be happy alone, but in need for others for my own security. The first person that cares for me is my mother. I love her because she cares for me. Although I build my relationships around me, I learn that my parents love me unconditionally.  In life, I reflect what I learned  from them and/or sincere friends. Then, when I suffer some calamity, some storm in my life, I  turn to friends and ask their help. In my relationship with them, I discover the value of true love implanted in Man by God.
The Third Degree of Love: Love of Man for Man's Sake
In the first degree of love we love ourselves for our own sake. In the second degree of love we love others for our own sake, chiefly because they have provided for us. But if trials and tribulations continue to come upon us, God sends us other people to brings us through. Even if our hearts were made of stone, we will begin to be softened because of the rescuer. Thus, we begin to love others not merely for our own sakes, but for themselves.
However, the truth is in God....
Without God who grants love, there is no true love because in my self-idolatry  I die. This is why I hope that God will save me and save everyone else in his eternal love. Saints are examples that reflect God's love for us and everyone in Christ, because Christ willed and trusted his Father...(For more reflection see The Trinity here).
