Yes, it May Sound Bad ...

Heathcliff sort of brought about his own death because of his sadness for Catherine. However, what confuses me is: why didn't he do this before? Why did he continue to live all those years after Catherine's death? All he did after she died was cause pain to others and spread his anger to those whom he should have loved. I just am surprised that he didn't die of grief earlier becuase ultimately, I think that's what caused him to be killed anyway. Perhaps it took him a long time to figure things out and come to terms with her death. Also, why did he casually stay away while Catherine was dying? He should have come to her (even though that would have angered Edgar). It was surprising to know that when Nelly told him the grave news of Catherine's death, he seemed to expect as much.
