I don’t know, has Putin killed(murdered) 40 Million or so people yet? How many People has Putin Sentenced to the gulags? I would say “No”.
This is a practice that still goes on in Russia, though I do not know if they are "gulags." Political opponents are frequently sent to prisons, some are sent to psychiatric hospitals, things of that sort, still others are just killed. Stalin, however, isn't the problem. The problem is the system. It is the Soviet system that has killed over 60 million people since it came into being, and is still killing through the hands of its heirs, of which Putin is just a figurehead of.
Yes, that was my reaction too. Putin has no doubt killed hundreds of people, maybe thousands, maybe even tens of thousands, but he’s well shy of a million, not to say multiple millions.
