What about Aniket?

So Aniket is supposed to stay in jail for 20 years? He'll be in his late 50's/early 60's by the time he's released! What kind of justice is that? Is there a chance he might be released before then when they realize that he couldn't have possibly been responsible for SV's death? I'm sorry but no matter what ultimately happens, I don't think true justice can be served if Sindoora goes 20 years without punishment while so many innocent people suffer. She should have been punished immediately and for the rest of her life.
