thoughts of end of life

If a person is diagnosed with a terminal (meaning no chance of recovery ever), They should be allowed to chose the manner in which they exit this earth. I believe that allowing a patience to determine the dignity part of "death with dignity" in nursing roles is a vital part of what is essesential to the holistic care of the person. Think of it this way: You just found out you had Huntington's disease and you are cognitively aware of all the pain and advanced care that it will require to continue to survive. It is wrong for you, as the patient to not want to suffer an existence, but decide to fulfill all the last wishes of life and live it to the fullest until the onset of the pain and inability to care for yourself happens? In this situation, and many others I strongly feel that it is the patient who should decide and if they (the patient) feels that the pain and inability to care for themselves is not "dignified" and then chose to meet death on their terms (instead of societally imposed terms) why not provide them with the assistance that they would need. Looking at Fidelity, I am true to myself because I would want someone to do the same for me, if that is what I chose. Beneficence comes into play because spiritually (again using the holistic approach) the person is at peace and often times inflicting a spiritual wound to someone is worse than a physical one. Nonmalefience again, if the culture, spirituality and mindset of the patient would be harmed by not assisting, aren't you providing the bigger harm?
