Early european murderers?

first of all Transylvania is in Romania. Secondly, Vlad the Impaler was by no means a murderer like Jack the Ripper or Bathory. He was a leader who killed Turks / Muslims in battles and used the means of his time to make a point out of it. In comparison, the crimes of the Inquisition were far more brutal during those times. At least he was a defender of Christianity. So you'd better do some reading first then ask your question
