We feel like there is a difference between those 2 cases because we experience a continuity in our experience of the universe (ie. consciousness).
Under this premise (as you stated), copying your entire state and spawning it elsewhere (then killing the original) means your original version experiences a stopping of their continuity.
But if you analyze that premise, you realize that the only reason we believe we existed a second ago is because of our memory (the same reason the clone believes it was always alive).
How can you know that you aren't being cloned, in-place, right now? ie. Copied, killed, and spawned in place almost instantaneously. At every instant you carry all your memories and thus "feel" continuity, but it's a new you.
In this view, being killed and spawned elsewhere is no different. It isn't taking anything away from you because you never had it.
Obviously this is just a thought experiment, but just the fact that right now, while you were questioning if being cloned and killed was bad for the original you, this process could have been happening to you without your knowledge, might mean it is irrelevant.
