Let me tell you a story from Indian history. Give me your perspectives on this guy.
So there was this cruel king from the Kingdom in Pataliputr (present day Patna, India) in the third century BC. His name was Nand. He insulted a person from the priest class named Chanakya. This guy was a mastermind. He goes to a village, finds a teenage kid called Chandragupt Maurya. He trains this kid, makes him able and then attacks the Kingdom of Nand, defeats him and installs Chandragupt as the king. This guy goes on to start the largest Indian Empire to ever exist.
So this guy Chanakya was definitely using this kid to fulfil his own interests. But his interests benefited this kid as well. Of course no deed in the world is a selfless deed but in this case, the kid barely had a choice and was just used. Would you think this act of Chanakya was justified for the kid ? What if he wanted to be something else ? What if Chanakya had failed ? Something to think about.
