Have you heard of Hazrat Abdul Qadir Zilani (R)? When he was eight, his mother sent him abroad to study in a famous madrasah. For his expenses she sewed 80 dinars inside his shirt. On the way, robbers got hold of the caravan and took everything from everybody. Just to joke they asked, 'does anyone have anything else?' The little boy stepped forward and said, 'yes, i have 80 dinars'. They were surprised, how could they miss such a large amount? They searched him again and found nothing. Just when they were about to leave thinking these were the ramblings of a little boy, th eboy tore off his shirt and showed the baffled robbers where the money was hidden. They asked him, 'you could easily save that money from us, why did you tell us about it?' He said, 'because my mother told me never to tell a lie'. The robbers felt ashamed in front of the little boy. They asked Allah's forgiveness for what they had been doing, returned everything they took from everybody and thereafter became good muslims.
So, you see, it is never too early to learn to assume responsibility for ones actions. If you read the chapter that describes how Heathcliff was first brought in by Mr. Earnshaw, you will see how Mrs. Earnshaw indulged Catherine and Hindley to illtreat the little child. Catharine only grew close to Heathcliff after her mother died and her brother became distant. They were brought up without any moral training but they were not interested in morality anyway as you will remember, Cathy used to kick her Bible when the curate came to teach. She never had any moral considerations and even when Nelly discussed the pros and cons of her marriage prospects, Cathy was more concerned about the advantages and disadvantages of each match than she was about what was right and what was wrong. We cannot excuse Catharine for what she did, Heathcliff could not forgive her either because she did it consciously. She wanted the name, wealth and status of the Lintons and the love of Heathcliff all at the same time. So, excusing her actions is out of the question. Just as you cannot excuse a little child who likes to beat other children and you have to punish them in order to correct them, you also cannot forgive Catherine for making a choice that ruined everybody around her and not even trying to make up for it.
Let us learn to take care of our actions for this life and the next.

Wuthering Heights is my favourite novel because of its experiments in unbridled human nature, its poetic prose, its technical excellence and its affinity to nature.
The point of Wuthering Heights is to show what can happen if one gives importance only to emotion without the restriction of reason or morality. So, it is not the point whether Heathcliff is right or wrong; that is quite obvious. What is important is that human beings should have moral and rational considerations in their actions. Otherwise inspite of their circumstances, they become monsters. Because even when you look at the relationship between Catherine and Heathcliff, you cannot justify it by any standard. They felt united in spirit, yet they married other people and ruined their lives! So, what we learn from the depiction of Heathcliff is what Shakespeare said, 'It is all very good to have the strength of a giant, but it is dangerous to use it like a giant'. This is why you feel sorry for Heathcliff's sufferings but you cannot stay with him in his revenge plan to the end. Revenge ultimately destroys the avenger and this is why Heathcliff ultimately loses in spite of winning and this is where his tragedy lies. He lost the purpose of his life behind revenge and lost the positive human qualities which he could have shown (as in his love for Hareton) to a devillish image. This is why we sympathise with Heathcliff inspite of what he turns out to be. Because we too are imperfect and we too would have done what he did if we had the power and the means.
But, you see, winning is not always a victory and losing is not always a defeat. The better human being wins under any circumstance. The worse succumbs to the circumstance
