regretting them with a sweeping superstitious

No one intruded upon her, believing that she wished to be left alone with her grief, but to be left alone was the last thing Scarlett desired. Had it only been grief that companioned her, she could have borne it as she had borne other griefs. But, added to her stunned sense of loss at Frank’s death, were fear and remorse and the torment of a suddenly awakened conscience. For the first time in her life she was regretting things she had done, regretting them with a sweeping superstitious fear that made her cast sidelong glances at the bed upon which she had lain with Frank. 　She had killed Frank. She had killed him just as surely as if it had been her finger that pulled the trigger. He had begged her not to go about alone but she had not listened to him. And now he was dead because of her obstinacy. God would punish her for that. But there lay upon her conscience another matter that was heavier and more frightening even than causing his death—a matter which had never troubled her until she looked upon his coffined face. There had been something helpless and pathetic in that still face which had accused her. God would punish her for marrying him when he really loved Suellen. She would have to cower at the seat of judgment and answer for that lie she told him coming back from the Yankee camp in his buggy. 　Useless for her to argue now that the end justified the means, that she was driven into trapping him, that the fate of too many people hung on her for her to consider either his or Suellen’s rights and happiness. The truth stood out boldly and she cowered away from it. She had married him coldly and used him coldly. And she had made him unhappy during the last six months when she could have made him very happy. God would punish her for not being nicer to him—punish her for all her bullyings and proddings and storms of temper and cutting remarks, for alienating his friends and shaming him by operating the mills and building the saloon and leasing convicts. 　She had made him very unhappy and she knew it, but he had borne it all like a gentleman. The only thing she had ever done that gave him any real happiness was to present him with Ella. And she knew if she could have kept from having Ella, Ella would never have been born.
