That is not so much sentience as it is consciousness. Sentience usually means the ability to have emotions and it makes you something. See we usually have no remorse from killing an insect because they are dumb as hell. They're not smart enough to think but mostly they don't have feelings. Evolution made them feel only fear, hunger and needing for reproduction. We cringe when we see dogs and cats being killed even in a video. Because they're smart enough to feel-even the simpliest emotions-so we can be atached to them and so can they.

Consciousness, on the other side, is an ability to have complex thoughts and being able to act against the evolution. Being death meant a lot of things in history: lack of pulse, lack of breath, but this things were present in many cases where people were actually alive. Now being dead probably means brain death where the consciousness is completly gone.

See, they say that in a close future we will be able to become immortal by changing the old body parts with cloned ones. "Good! Now much do you think the brain will resist dumbass?", I thought because even an identical clone, a perfect clone will still not be you. Your consciousness won't just go in the other body there when you die. This works similar to the biomechanical things.
