Bajaj was evil, is evil and will remain so. But I would say there’s difference between Komolika and Bajaj. Though both are bad, Bajaj is worse. Komolika is true villain whom one can enjoy as she’s honest villain character. She isn’t fake and doesn’t pretend to be saint. Bajaj, on other hand, is the worst. If Komolika is villain, Bajaj is the satan and the parent of Komolika. If Satan is real, then Bajaj fits the description of being treacherous, fake, and acting saint while evil in real. S1 Bajaj must be having his time in hell. That despicable evil person deserve just that while crying over Anupre being together forever. And this Bajaj will lose too in the end. He will temporarily fly and then go to his hell where his home is for forever.
