Sorry FOR?

There's a difference between

1." I'M SORRY FOR WHAT I'VE DONE THAT CAUSE YOU THE PAIN" 

2. " I'M SORRY FOR WHAT HAD HAPPEN"

1st sorry is that they realise what they had done is wrong and it has cause you the pain that you shouldn't or not deserved to go through. They have sense of remorse for the pain they cause others.

2nd sorry will be they are sorry for WHAT HAPPEN.SELFISH person that doesn't even had the slightest sense of remorse for their wrong doings that cause you the pain. AND STILL thinks that they are the righteous ones and it's your own fault you felt that way. Just to save their own ass.. they thinks its okey to do that to others. OR THEY ARE JUST SORRY FOR THEMSELVES that they are BUSTED.
