In King Lear, Regan and Goneril are painted as the ultimate villains. They betray Lear, are power-hungry, step on their husbands to get to Edmund, and Goneril ends up poisoning Regan. There’s no denying they aren’t angels, but when you consider what their lives have been like I don’t think you can blame them.
First of all, Lear only becomes an empathetic, unselfish person when he has his revelation near the end of the play. We only know him for the duration of the play, and even then we’re frustrated with how stupid he is for the majority of it. This is a man who makes his daughters compete to profess their undying love to him before he’ll give them their inheritance and is dumb enough to believe what they’re saying is true. He clearly has no regard for others because he only realizes he should have been helping the poor out when he is out in the storm with no shelter. Regan and Goneril are middle aged when they finally get their inheritance, which means they’ve been forced to be subservient and respectful to Lear for like 40 something years. Not to mention, Lear makes it clear Cordelia is his favorite daughter. They’ve probably been compared to their perfect, gentle, beautiful sister their whole lives, which would make anyone bitter. If I were them I honestly would have put Lear in a home as soon as I got my power. It’s not like he was a good king or father, so I don’t see any reason why they wouldn’t.
Additionally, Regan and Goneril seem evil because of their lust for Edmund, but let’s remember that they’ve been forced into marriage with Cornwall and Albany for probably 10-20 years. Cornwall is clearly a jerk, as we saw with his treatment of Gloucester. I think he and Burgundy would’ve been friends because he’s just in it for the power and money. Albany seems like a good guy, but there’s no way Goneril was in love with him. She’s super ambitious and he is a bit of a pushover. There’s nothing wrong with that, but I see it as a successful female entrepreneur being forced to marry a guy who plays video games all day and doesn’t have a job. Furthermore, based on all the bastard children, it seems like it would be likely Cornwall and Albany just called up the village prostitute whenever they wanted. Regan and Goneril were living their lives completely sexually repressed and married to (probably ugly and old) men they didn’t love. Why wouldn’t they go after after Edmund?
