As soon as we lose our compassion for one another, we lose our humanity.
Compassion is what separates us from the animals.
Of course, we do not need compassion to have intellects or free will, but these are wasted without it.
Without compassion, we are not much more than overly intelligent beasts determined to destroy ourselves and one another.
Compassion should guide our intellect.
Compassion is the proper use of free will.
Once we have lost our compassion, we have lost our way.
