Morality is only meaningful for the species which can understand their actions and their consequences.
For example, rape is a very serious crime for humans but it is not used for animals. Rather, forced copulation is the preferred term to explain such behaviours in the animal kingdom. (There is an ongoing debate whether dolphins are raping or force copulating, but that is another issue.)
Cats give importance to their own personal space. It doesn't mean that they reciprocate your need of personal space. Some of them are known to be selfish and love to dictate the relationship with their human companions.
Another issue is that since you have the mental capacity to understand actions of a member of another species, you know that the cat wants to be left alone. It might not be the case for the cat. He might not understand that you dislike his behaviour.
It is also totally possible that he understands it, but doesn't care at all. After all, unlike dogs, they don't need to obsessively satisfy the alpha.
If you really want him to know you are annoyed by his behaviour, here are some tips. Don't forget that you have to do these things as soon as he wakes you up, otherwise he won't make the association.
