Bronte has confounded many literary experts with the subtleties in her narrative, and by 'missing out' key facts such as this. The result is that at the end of the day, Wuthering Heights involves a lot of participation from the reader, and it is really whatever the reader makes of it rather than a clear conclusive message from the author.
In my opinion, the underlying meaning behind this statement is that Heathcliff cares more for Cathy, gives her more importance, than he does himself. He can forgive her for anything, however atrocious, but anyone who hurts her, or tries to hurt her, he can never forgive. It shows the very extreme of love where for him, Cathy is almost sacred, can do no wrong, and must have no wrong done against her. (A bit creepy but also romantic)
Reason and logic compel me to believe that Heathcliff can forgive Cathy (his murderer) but cannot forgive himself (Cathy's murderer), as my above hypothesis of how he can always forgive Cathy would otherwise not stand true. However, reason and logic have very little, if anything, to do with this book so I guess my guess is as good as the next person's.
