Mr Earnshaw (Wuthering Heights) means well, but he's a poor specimen. He scoops his little foundling off the streets of Liverpool, then dumps said foundling on his wife, who hasn't the least idea what to do with him. The outcome is dreadful for Heathcliff and everyone connected with him. If Mr Earnshaw had taken Heathcliff in hand while he was still a lost little mite, things could have been very different. Of course, there wouldn't have been as much of a story.
Mrs Reed (Jane Eyre.) Her mistreatment of Jane is shocking enough. The way she pampers her son and allows him to tyrannise the household (especially Jane,) is exactly why he grows up feckless, wasteful and horrible and dies an early death. Her daughters regard her with disdain and who can blame them?
