How can it be bad to be murdered for the person who is murdered?

Let's say someone kills you painlessly in your sleep. Let's (for the sake of argument) assume you enjoyed being alive and hence would now be missing out on a few "good years". But how can being deprived of those good years be a bad thing to a person who is now dead? It seems to me that dead people can have no preferences and that nothing can be either good or bad for them, seeing as they now no longer exist.

It seems like you think it can only be bad to be deprived of something if you can experience the the deprivation, right?

Well? We might just reject this idea and say that it’s bad to be deprived - that preference violation is sufficient for badness or else incorporate such a provision into how we conceive of hedonistic happiness.  (Singer’s preference utilitarianism and, later, his hedonistic utilitarianism allow for this.)

Nagel has an essay called “Death” where he addresses the problem (some people find it a bit wanting).  Roughly, he argues that these requirements (that we need to experience something for it to be bad) don’t stand up to common sense cases where we’re wronged while ignorant of it or else a bunch of our common sense preferences don’t make any sense at all.  For instance, as a matter of course, we have preferences for things that we can’t check up on even while we exist.
