Why is almost everyone turning evil in this series

Ganga has turned from a meek, passive person to a MIL from hell, and she seems to all of a sudden have all the power in the house, the BIL, is turning evil, the Aunty and Uncle and Cousin are evil and her FIL is pure evil...cant there be a good balance? Maybe just 2 evil people..and the sudden change of charactrs are unbelievable

You right Pinky Tuntun, Pinky dad, Pinky mom, Pintu mom, Krishna brother in law

that's what driving me away from watching AB. there are too many negative characters - at both homes , in the office , in the community, and krishna is no superwoman with superpowers. the story is becoming unrealistic.How could an ordinary woman fight them all alone ? If I were Krishna who was so talented and smart I would resign from this gov't office and just work in a private company and receive a higher salary and with less enemies.
