She unleashed her fury and drank Raktabeej's blood...what they have shown in the serial is by mistake.. But even after that her fury did not subside ..she just could not control her anger...and her destructive mood..Devas were scared,begged Mahadev to do something..Mahadev laid down amidst the corpses on her way..and she stamped over him.The moment she stamped on him with one foot,she realized what she has done,and her fury evaporated ...and she became repentant that she had stamped on Mahadev's chest. This is as per Devi mahatmyiam..which I read regularly during navratri.
I dont know if there are other versions ..
Kali is considered the 'forceful' form of the great goddess Durga.In the ignorant ones she creates fear, while for others Kali removes the avidya (ignorance) that makes us fear death, the basic insecurity of the First Chakra, a fear rooted in the brain stem or primitive brain.
