Edgar Linton - his initial snobbishness toward Heathcliff fuels the latter's revenge. He marries Catherine, not because she's a lady, but because she's beautiful. This is evident the night they profess their love for each other: Catherine throws a temper tantrum, including grabbing Edgar's face in anger. Edgar walks out, threatening to never return. As he approaches the gate, he turns and can't help notice Catherine's beauty. They make up.
Edgar does prove himself a worthy, albeit, physically weak husband, who slaps Heathcliff and runs away to get servants so Heathcliff doesn't beat him up. After Catherine dies, Edgar demonstrates an inner fortitude, heretofore unseen. He provides Catherine a good home, yet is too weak to prevent Heathcliff from encroaching on his property and family.
Isabella Linton - She may be the dumbest girl in all of literature. The man to whom she pledges her life hangs her puppy on the day they are to elope. She still marries him.
Catherine Linton - The daughter of Edgar Linton and Catherine Earnshaw, Catherine Linton's disobedient, petulant nature condemns her to a forced marriage with the most despicable man to ever grace the pages of Gothic literature (and it's not even Heathcliff). Luckily, her whiny husband dies and she redeems the family with a good second marriage.
Linton Heathcliff - Linton inherits the worst traits of both his parents. He is whiny, weak and stupid like his mother. He is imperious and demanding like his father. Linton is so annoying that I began to enjoy reading about Heathcliff torturing him.
