Assuming you weren't alive when those decisions were made or did not support them at the time, I don't see why you should. You have little control over the actions of your nation-state today, you had none when those atrocities were being committed. The vast majority of the people alive today bear no responsibility whatsoever for the events of WWII

I agree with first 2 sentences but have to correct: his societies were outlaws and KGB (legal outlaws) which is far from representing the whole population.
Putin's both parents worked at a factory which means no parents most of the time, the daycare was provided by the "criminal elements" [sic] on the streets, he stated that he wanted to join KGB during childhood, he didn't pass entry exams as he entered university as a sportsman and became KGB's agent (not an employee), his job was KGB then after the fall of Berlin Wall he worked for rector of his uni for a brief time and after that for a docent who went into politics and happened to become the mayor of now St. Petersburg in 1991...
