The purpose of bioethicists is to formulate excuses for those who desire to kill human beings, for one reason or another.
The main focus is to create a system in which human value becomes dependent on relationships or to job function. This places the unborn, disabled or very sick human beings into very killable categories.
A really effective bioethicist can make a person feel much better while contemplating the killing, as well as in the aftermath. Inventing creative uses for the bodies of the dead helps to expiate the guilt that normal people used to associate with killing other humans. So this has become a significant corollary field of bioethics.
