Blaming Tulsi for Savitas murder

Okay, correct me if i'm wrong.  Wasn't not proven when Tulsi came back, Meera confirmed in front of everyone that she planned and got Savita murdered?  Now Maher and now Gayariti have once again stated that Tulsi killed Savita (Last episode Maher brought up Tulsi killing her son and his mother)  However, right in front of Maher it was said that Tulsi did not kill Savita that Meera killed her, because Savita found out the truth about her.  So why do the so Called Creative writers keep putting this in there, does this not bother anyone?

Meera murdered Savita. then she was sent to the hospital and her condition was critical. they doctors said that if Savita contiued to live she would live a very painful life. The doctors told Tulsi they best thing to do was to pull the plug but Tulsi refused to. ( The rest ov the viranis were off to London for Suhasi's sons wedding ). Savita cofronted Tusli and told her she should pull the plug and its better for Savita and she can go peacefully live in heaven. Savita also apologized to Tulsi and they shared such loving moments before the plug was pulled. Tulsi did pull the plug but only because thats what Savita & the doctors wanted. and then the ***** Gayatri always has to blame Tulsi
