Is Past Life Regression Ethical (Part 1-4)

Above, is the title of an article written by Gabriel Andrade from the Journal of Medical Ethics and History of Medicine.
Gabriel Andrade’s argument is two-fold.
First, she states that past life regression is not evidence-based.
Second, she states, “past life regression therapy has the great risk of implanting false memories in patients, and thus, causing significant harm. This is a violation of the principle of non-malfeasance, which is surely the most important principle in medical ethics.”

I am going to be the devil's advocate on this one and ask some questions. 
First, let us consider the following:
Reincarnation is a central belief of many religions

• Hinduism 1.2 billion

• Buddhism 535 million

• Jainism 6 million

• Sikhs 25 million

• Kabbalah Judaism?

• Americans and Europeans ( estimates from various countries range from 12% to 44% )
  If you do the numbers, this adds up to approximately 2 billion out of a world population of 7.8 billion. 

As reincarnation and past life regression are closely related, I would hypothesize that both concepts also include unique, distinct, belief systems. It is also not within the scope of this review to discuss how each religion views reincarnation.

The article, to me, reads that since there is no scientific proof of reincarnation, then past life regression does not exist. 
My first question: As religion is not evidence-based, is it unethical?
If we look at her second reason, i.e. “it implants false memories,” then I would ask the question -  does the process of past life regression therapy require you to implant false memories?

This is such an interesting subject, so I have decided to divide it up into four parts. The last part will be my personal experiences of facilitating PLR and my theory of what is happening during such sessions.

In Part 2, we will look at some history of PLR and look at the work of Dr. Ian Stevenson MD and Dr. Brian Weiss MD. These two respected scientists are the leading authorities on PLR.
