The explination for his behaviour is quite simple and doesn't necessarily have to be explained through disease: his childhood spent on rhe road through Western states and then at the Sultan Murad the 2nd court. He saw lots of violence and hated obedience towards the sultan. Of course he wanted to impale just about any ottomans after that. The rest are stories made up by the tradespeople who did not want to pay taxes to him.
