Forgiveness is Neccessary

What if you had the choice of watching your friend die by death of an angry mob, or kill him yourself to relieve him of his pain? I believe if you chose to relieve your friend of his pain that you would feel guilty even though you did the right thing. Forgiveness is key to a person that has gone through this situation and they deserve more then forgiveness. A person in this situation needs people to tell him or her that they did the right thing. They are good people, of course they deserve forgiveness.
