Did Maya do any sort of like that, did she harm Saanjh, did she made her kidnap, tried to kill her, before you all say about holi, lets say not Maya but will world keep quite seeing Dusky duffer's drama. Maya has caged Jhanvi for a reason, if you guys don't remember let me remind you when Jhanvi was in hospital, Whenever Maya sent her mother out, something happens to her and who has to bear the consequence.
If people who are tagged as mad and think mental asylum is the best place even though having families what does the humanity mean. Will you just leave that person dying only because you think she will someday kill you,
