I know I am not anyone to judge but I think we should stop white-washing the criminals. All the stories show that they were once an angel but some unfortunate incidents turned them into devils.
YES , I believe something terrible might have happened in your life but that doesn't gives you the right to hurt innocent people. If the person is really an angel then they will never hurt or blame innocent people for their misery. Just take the example of our Idols, the people we worship. Shree Ram, Mata Sita..they all suffered in their human life but never blamed or hurt anyone or at least show displeasure for their sufferings to people, they lived their life, faced challenges and set examples of their life that till today people worship them. Wasn't it easy for them to put blame on other and move on rather than suffering unimaginable pain but No, they suffered. They are the real angels.
Just my opinion. It's okay if you disagree.
