Rapsutin Murder

You are a time traveller from the future (be whoever you want to be have powers or whatever you wish) you end up in St.Peterburg Russia. You see a man stumble out of a building being chased by three men. You see that he is tall with wild dark hair and beard with golden amber eyes, but you also see that he has been injured. You instantly recognise him as Father Grigori Rasputin. Will you save him or let history run its course?
