Answer and Explanation:
I cannot provide you with a whole essay, but I can give you some starting points concerning the two characters in "The Great Gatsby", by F. Scott Fitzgerald.
The similarity we find in Tom Buchanan and George Wilson is basically their sexism. Both characters perceive themselves as the rightful owners of their wives. Women, they believe, are somehow inferior to them in hierarchy. They must be faithful and devoted to men as their husbands, even if those very men are not faithful. To Tom and Wilson, women are supposed to conform to whatever life their husbands choose to give them, enjoying their freedom only up to the point where they don't interfere with their husbands' lives and pride.
They are also both violent men, but in different ways. Tom is more powerful in a psychological way. He is able to influence his wife, Daisy, through psychological intimidation, alternating his violent verbal outbursts with quieter expressions of love. Instead of beating Daisy up, he makes her see him as a "true" man, a man who loves her so much that he has other women in his life, but never leaves her. On the other hand, he does not show the same consideration for his lover, Wilson's wife, Myrtle. Even though he cares about her, he does not hesitate to slap her when she offends Daisy. He thinks he has the right to discipline her through physical violence, something he would never do to Daisy - his main girl.
Wilson, in his turn, does not possess the same psychological power Tom does. Upon finding out he is being cheated on, Wilson gets sickly desperate and chooses to force Myrtle to move away with him. That is, in itself, a form of violence. He thinks he is entitled to determine his wife's life and, instead of trying to convince her to change her attitude or simply putting an end to their marriage, he decides he can simply force her to do as he bids.
