After everyone is born, an angel is born, that is... A guardian angel.
The rule of guardian angels is to protect their master, that is, the person they are guarding. If the master is injured, his angel will be punished because when their master is in danger, they will minimize the damage. They will appear to protect their master when they have to, but few angels will do their duty...
