Obama was attempting to take out terrorist leaders who had declared war on the US and the West and acted on that.
Critics claim 803 civilians have died in these attempts.
Putin? Wikipedia, Second Chechnya war:
Estimates of casualties in the
Second Chechen War vary wildly, from 25,000 to 200,000 civilian dead plus 8,000 to 40,000 Russian military. (Separate figures for Chechen military fatalities from the second war only are not yet referenced in this article.)
Note: Some of these figures include the
First Chechen War of 1994-1996. They usually don't include the death toll in
Dagestan,
Ingushetia, and other neighbouring regions of
North Caucasus, where the violence spilled-off from
Chechnya.

And of course, war in the Ukraine. And the war in Georgia. Plus support for Syria's dictator and his murderous ways.
So when you look at the numbers, Putin and by a huge margin.
It seems as if a lot of people think Obama should not have pursued al Qaeda leaders. Well, no. Letting them have free reign would be stupid. But Putin, first thing he did as new leader of Russia was attack Chechnya.
