Wuthering Heights

I have spent the entire weekend reading WUTHERING HEIGHTS while waiting for the damned typhoon to be over, in this novel I have witnessed a true living devil under the name of HEATHCLIFF. Is he a force of evil or simply a victim of it?
Heathcliff: Catherine Earnshaw, may you not rest so long as I live on! I killed you. Haunt me, then! Haunt your murderer! I know that ghosts have wandered on the Earth. Be with me always. Take any form, drive me mad, only do not leave me in this dark abyss alone where I cannot find you. I cannot live without my life! I cannot die without my soul. 
-This line made me hang in the mid air!!!! Then I thought If I had a lover like HEATHCLIFF , it would be a living hell since it is better to be hated than to be loved by him. Why did he kept on living for another 19 years after CATHERINE had perished? If this kind of LOVE takes place in this modern world today, how cruel would that crazy little thing (called love) would be, full of obsession, passion and revenge? I dare not to speak of it!!!!!
Catherine: If all else is perished and he remained, I should still continue to be, and if all else remained and he were annihilated , the universe would turn to a mighty stranger, I should not seem part of it.
- This reminded me of EDWARD CULLEN, the extent of his action due to Alice's false vision of Bella's death. Yes, I did read the twilight saga. I know that these two novels cant be compared but the message that their characters convey is the same in a way, DEATH AFTER LOVE..... Tragedy is a tragic thing but if the idea of love is mixed, it transcends to romantic. These people depicts love as if there is nothing that would come after it if the object of their affection have reunited with the earth. Is it really that way? That there is nothing that comes after but misery and the world would turn into an abandoned wretched space?
