Cleo Judson, The Living is Easy by Dorothy West
Cleo was a selfish, , manipulative woman that had the ability to do so much more with power. Many readers feel they have an obligation to hate Cleo because she preyed on anyone who she deemed weaker than her. Her manipulative schemes to lure her sisters away from their husbands made it morally obligatory to hate Cleo even more. West produced a character that should be a cautionary tale to anyone who suffers from self-delusion.
