Rudra is considering himself innocent because Anand told the court that when he fished abhi out of the pool, Abhi was still breathing and when they reached the hospital,the doctor said that abhi needed an operation and anand went to get the medicines and that when he returned he was told that abhi is dead.
So Abhi death was caused in the hospital not in the pool thus rudra is free of blame.
One thing of interest is that abhi died of drowning as his lungs was full of water and rudra shdnt be blamed because he died in hospital. How contradicting!!! Also abhi wouldnt have died if rudra hadnt left him in the pool.
