Well I guess you're right about the story being rushed and also that there was too little introspection of all characters as of lately.
What irritates me in Babita that besides her conformistic tendencies she did have a caring side to her which I thought just as central to her character as her impuksivities. She did act very impulsively and also barely knew her considering finances e. G when she made that dress for Minnie, but she did it with a caring attitude. I can't fathom what happened to this side of hers.
Who says Babita’s caring side is totally gone? She is still a very caring person....a good person.
What the story is showing is the fact that our personality flaws can take over our good traits some times. This is quite a realistic thing. Doesn’t mean her caring nature is gone....it’s just overpowered by other things for now.
She will realize her mistake eventually but by then a heavy price will have been paid. This happens in real life also when our character flaws end up messing our relationships.....no one is perfect.
