The to carry one out soon, due to

The cost of such a surgery would be between $10 million
and $100 million, so people may say that this money would be better spent on
helping people who suffer spinal cord injuries, which is a huge number. Head
transplants also raise issues of who the new body belongs to, so if someone
with the transplant had a child, would the family of the donated body have
rights to see the child and be involved with its life? There’s also no
certainty that someone would be able to accept a new body as part of
themselves, for example, the man who underwent the world’s first hand
transplant was uncomfortable with his new hand. So, he stopped taking his
immunosuppressive drugs and the hand had to be surgically removed.6

If the patient does die due to the risky procedure, does
it matter if he has consented to the surgery based on the chance that a
successful head/body transplant could enable him to function ‘normally’. This
is along the same topic as euthanasia and assisted suicide, and these can be dealt
with by a punishment of three to ten years of imprisonment for intentional
homicide and in some countries, would lead to at least 10 years’ imprisonment and
up to the death penalty for more serious crimes. So, if the patient was to die,
then would it be classed as euthanasia, which is illegal in the UK and is
regarded as manslaughter or murder, punishable by law up to life imprisonment.
There would also be a great possibility of a public uproar due to the ethics
involved in such a procedure. 

Furthermore, the risk of anything going wrong in the
transplant procedure is very high and at this moment in time we don’t know
anywhere near enough to carry one out soon, due to this, the risks of such a
procedure may outweigh the benefits. This is because there is a huge risk that
something may not go to plan and therefore two lives will be lost, lives which
are sacred in religious beliefs and so we don’t have the right to temper with
them or take them away. To go on with a head/brain transplant, it should be
voluntary, the brain/head should be donated and it should be a last-resort
operation as it may be the lesser of two evils and really help to improve the
quality of someone’s life who suffers from a severe mental or physical
life-threatening/altering disease. In addition to this, the huge amount of
research needed would cost a lot of time and money, but I believe that it would
be worth it in the future as medical technology advances, but it may lead to a slippery
slope, where lots of lives are lost and transplants like this happen on a
regular occasion to people who don’t really need them and ‘waste’ a huge sum of
money and resources.
