Pay for what you did. This world is not cruel but just like that. If you want anything, you have to pay for it. If you do something either good or bad, you have to bare the outcome with no complain.
This kind of idea is very obvious in Islamic country because their law is kind of 'pay-back'. If you break other's arm, you will be sentenced to break your own arm. In this civilisation time, this kind of idea is against humanity. That's why many of human right association against it.
However, we do have to realise that what you do has it own outcome and you will have to take full responsibility. There's another idea called KARMA which we pay in the next life.
As conclusion, we all have to think before we act so that we won't have to bare the terrible outcome.
