He certainly was sadistic. He liked to impale people and then watch them die slowly. Often dining and entertaining guests under the people on stakes.
Supposedly one guest complained of the stench so he had him impaled higher than the others so the stench wouldn't bother him anymore.
He also invited every beggar, cripple, and mentally disabled person from his village to a feast. He asked if they were happy and if they would rather never have to work another day in their lives. After everyone cheered he left the hall, locked the doors and set the hall on fire so there were no survivors.
He was obsessed with honesty. he kept a gold cup at the fountain in the centre of the village for all to use but no one ever stole it because the punishment for stealing was impalement. After catching a group of boys stealing apples, he ordered them buried alive with air holes and some water. He said that he wanted them to eat each other to survive and that the last boy to survive would be set free.
After he was imprisoned, he enjoyed torturing bugs and small rodents the way he had previously tortured people. He impaled them on small sticks.
