The capacity for empathy, is not common. Most people can have sympathy, and some not even that.
I always know when I am dealing with someone who either has, or does not have, the capacity for empathy, by their responses to suffering.
Those who do not have empathy, will often give unwise, hurtful, harmful advice, and some will make the situation all about themselves. Or respond in a very selfish/self serving manner.
The capacity for empathy, is a truly amazing gift.
Empathy is something I am teaching my children, because the world needs more empathy and wisdom.
And you have to have empathy, to be able to model and teach it.
