We as humans cannot change the past. We cannot change the future. Neither past nor future is real yet. Only NOW is real. If that someone is attacking you maliciously and stands to harm their own Karma in their actions, you can assume a position of authority and with love in your heart, seek to assist them taking whatever means necessary to aid them in desisting in their negativity.
Freedom is also wrought with danger.
Were we to have a truly free society, where laws were few. We could go to a pharmacy and order whatever we needed without having to go to a doctor to beg for a prescription. The doctor s pride gets involved should you request a certain treatment, or medication the doctor will prescribe an alternative due to pride. If our free society were replete with responsibility, pharmacies could be open to all and a two week wait for a medical appointment would be alleviated the medicine just down the street. And the doctor s appointment could be a follow-up, reducing the patient s pain for up to 14 days.
