Your claim is that life demands the desire to live. I think ignoring the everyday cases where that's not true gives your critical thinking a bad foundation. I also provided many other examples. Every person is built on the backs of thousands of people. My brain was developed by thousands of ancestors and filled with the knowledge of millions of other humans. Yet I'm capable of not fearing death. But that aside, an artificial consciousness will be a whole new ballgame. I don't think we should assume the way we are is the way it is. That any consciousness will think the same.
