You believe propaganda. Why you believe it, I don't know.
Most "horrific" stories about Stalin are fabrications from the US and other anti-Russia nations. Sure, he was not a saint, but far from what the West tries to portray him.
Some info from your favorite US-sponsored and controlled propaganda outlet:
A total of 70 percent of the Russians surveyed said that Stalin played a completely positive or relatively positive role in "the life of our country," a jump from the 54 percent recorded in 2016, according to results released by independent pollster Levada Center on April 16.
Respect among Russians for Josef Stalin rose sharply in the past year and hit its highest levels since at least 2001, according to a new opinion poll.

"Holodomor" (famine allegedly deliberately caused by Stalin in order to exterminate Ukraineans)? It's one of the biggest lies fabricated by the West. There was famine in the area, but there was famine also in Russia and other areas of the former USSR.
The Bengal Famine is far better documented as being the result of Churchill's decisions.
