I can't feel remorse or guilt?

When something like a child starving is brought up. I can't feel sorrow. I feel bad for the kid, like that'd be rough kinda way, but I don't feel brought down or sadden. While everybody else claims these feelings. Only when it's with people I know can I truly feel remorse or guilt and when I do it's such a strong feeling. But I also have depression and tend to feel down all the time. I have a dad who's rather abusive (only verbally now) and an all around bad person to everyone. Is my depression in the way of making me feel sorrow since I'm already feeling it or am I just cold hearted?
