Did she forget that gauri was also some family's respect and pakhi's saintly parents fed lies to gauri's husband and proved her characterless in his eyes?
Kamla herself has no respect for her daughter.
If instead of looking at raghav as the villain, she had tried to understand what raghav's family went through and tried to understand her daughter' a love she would be a better person.
But no she will doubt gauri/raghav/kalpi but will consider kapoor a saintly.
Kamla is the root cause of all problems.
