Because he was a yindoo kafir baniya. That's why he said that.
And brother, I am not in denial. I am sharing my first hand experience with you. But promise me you won't tell this to anyone, deal?
Like I said, his real name is Ashok Kumar. His father's name is Bhagwan Kumar. But I am sure he was not remembering his father as he was not on good terms with his dad. His dad did not give him money to buy new cloths on Diwali. So he left home and went to a Jewish family. They also turned him down. This is one of the reasons he suggested that RAW should kill those Jews in Chabad House during our Mumbai drama. Also, he was a great fan of the book called "Mein Kampf" by Adolf Hitler.
And as for killing his fellow yindoos, he was a Dalit. He hated us upper caste yindoos. He always wanted a separate homeland for his Dalit community of Indian subcontinent. He also told us that the Dalits should name their new country "Dalitistan" with a capital called Dalitabad. He was planning a "Direct Fiction Day" to carry on with his "2 Fiction Theory."
So you see, he was become dangerous for India too. Initially we thought that we will use him for his entire life but his thoughts were very offensive to majority of our upper caste yindoos in RAW, so we hanged him.
