Guru Drona, the son of great rishi Bharadvaja. Who trianed Arjuna to be the greatest archer in the world. He was a great guru and a great person until the moment his love for his son clouded his thoughts. He clearly kept getting manipulated by Ashwatthama and kept following Adharma. It is safe to call him a Dhritarashtra with eyes. Infact he chose to close them when his son did wrong deeds. I won't say he didn't try to stop him but his cunning son kept on manipualting him. And finally his death was because Kanha manipulated a fact and he fell prey to that. Your thoughts guys. I think if you liked it. I wil bring a series of this. One person from Mahabharata daily.
