Empathy is one of the greatest emotions you can display to help another. When you are empathetic, you solve a sufferer's greatest problem, that he is alone.
One of Moshe's greatest qualities was his capacity for empathy even for those in situations vastly different than his own. His empathy pushed him to leave the comfort of Pharaoh's palace, where he was raised, and go out to see and feel the suffering of his people.
This was critical to his development as the future leader of the Jewish people, as well as being the trigger of Divine empathy that caused God to see and feel the depth of the Jewish suffering bringing their redemption.
"Moses grew up and went out to his brothers and saw their burdens. Rashi: He focused his eyes and heart to feel for them." Exodus 2:11, from this week's Torah portion, Shemot, Exodus 1:1-6:1
