If Vikrant is alive , then revenge is meaningless

Bela is on her revenge spree she already targetted Karan, Yuvi & Rehan. Karan is in coma , Yuvi is assumely dead , Rehan is dead, next is mahir .

If Vikrant is alive then this revenge is meaningless , infact killing of Yuvi & Rehan is not right then, they should be punished 4 sure but death really.

How will makers justify these killings ??
