No, it's not. Saying things over and over again do not make them true.
If it's murder, then why are there not thousands (millions?) of people in prison for carrying out their power-of-attorney duties in this way?

Why are there not countless hospital and nursing home employees imprisoned for not force-feeding dying patients?
Because it is not murder.
