Rajiv Gandhi’s killer did it out of personal vendetta. It is different from people who are misled.
Yuddhishtir’s example is not the correct example in this context. He was not misled. He did it out of his own free will for which he needed to pay the price. The disastrous consequences of his actions might have been a direct punishment for his actions.
That said I am not sure, how God in His infinite wisdom would react to people who are misled. It might be something that we have to wait till we are dead to find out.
