Get your facts right before writing your imaginations. Understandable you worship Tapasya, but that does not mean you need to degrade Ichcha. Both women are at their own places. If Ichcha is shown kind natured and mahaan, and Tapasya as a tramp sleeping purposefully or unintentionally, it's not your fault. You don't need to defend her or justify her as good by saying false info about Ichcha.
