[Karlozkiller]

I did find the experiment a bit more eerie than 'killing for food'. But that aside, some of the ethical problems they discussed in the article were regarding whether the possible revival of ones brain would mean that the person and his juridical status as a person would also follow, as well as his thoughts etc.

As opposed to if we experiment on some dead persons liver, if we experiment on his revived brain we might actually be experimenting on a conscious being (human), is what I believe is the main thing here.
