Vladimir Putin is a generally good person, everything he does is pretty much to help out his country.
for the 8 years he was president he basically pulled Russia out of a terrible economy and increased their average wage from $80 to $640, while increasing the average workers rights and such.
He is generally looked at as "evil" because of most the western worlds grudges/misconceptions against Russia.
But as a leader there has probably been noone greater in the last 50 years. He also spent most of his presidency at above 65% approval rating, most of the time around 80% with his highest at 85%, which is more than any other political figure ever.
