Sorry is a super 
word. It can relieve the anger in somebody almost at once. This word is used by many people around the world to apologize and ask for forgiveness to the God. For example if we do something wrong to our girlfriend, we can apologize and if the request of our forgiveness is accepted by our girlfriend that problem is finished.
But practically we cannot easily say sorry to other people, because we have to be serious and make a promise in order do not repeat it again. But many people apologizing insincerely and only wishing to finish problems and most of people will repeat the problem again. Besides that, sorry is also used to people who wish forgiveness to the god.

Yes sometimes this word is out of context. For example if someone said that he/she is sick then the response is I am sorry. To me this come across as being pitiful. This word should go back to its exact meaning and then person will genuinely accept it.
