Not all living things and not always. Some of them sacrifice themselves when they'll serve the purpose. Fear can be understood as simply wiring that influences the behavior so that an organism is less likely to die. That's how I see fear of death. But sometimes death of an individual is a better solution for the group, or even for the organism itself. The problem with humans is that we have somehow developed a view that death is the ultimately worst thing to happen, and we evade it with all our imagination, trying to find elixirs of immortality since we are aware what's going on, no matter what, not matter the cost other species pay for us. We don't see our limits and that's our problem, because we think we're exceptional and we deserve everything because of it. And it's very, very egocentric. We are not exceptional, in the sense that we don't automatically deserve more because we can paint pictures or compose music. We value ourselves based on things that don't even matter to other species. Instead, what we should do is to accept the responsibility that comes with the effectiveness of our brains, and figure out how it fits in the bigger picture of the ecosystem we're living in. But all we do with it is we exploit everything, making it serve us, because "we're exceptional and we deserve it". Even in this thread it's visible, people don't even spend a minute to consider this: 'whhatt?? humans not exceptional? i don't see any animals thinking about their exceptionalism, haha!'
