I just don't understand or relate to Maya's revenge plan. She had a normal childhood that allowed her to dream, love and nurture. She is not a sociopath and it is not easy to kill, especially those who is not the cause of your misery.
A psychological warfare with MJ, where maya takes away his support systems one by one and completely alienates him is so much more fun. MJ thrives on control and what is better then taking away that control? where his sons will see him for the evil he is and comes to destroy him? Rudra doesn't know how truly evil his father is. the incident with his GF is only tip of the iceberg.
