Death might harm you even though you'll never be alive to feel it
Epicurus argued death can't be bad for you, since you won't exist to suffer it once it happens. Thomas Nagel countered in 1970 that death is bad precisely because it deprives you of the good things you'd otherwise have gone on to experience — the 'deprivation account.' On this view the harm doesn't need to be felt at all, only a life cut shorter than it could have been.
