Was Stalin a selfish, power hungry leader, or did he do what he did for the good of CWatch
In terms of domestic policy of the USSR, I think his policy of collectivisation was a good policy, but the way he carried it out was to be sniffed at. I also think that the 5 year plans were successful, up until the point where we can see that people were that scared of him that they didn't do anything but obey - which threw the USSR into turmoil.
As for the great terror, well, you could argue this one both ways. You could argue that it was bad because of the humiliation he showed through the show trials and how he conducted them, as well as using Yagoda's conveyor belt system of torture to get people to confess. But, then, in the same way Stalin protected his position and again, if you felt threatened you would do the same thing, just not on the same level I would hope!
People argue that Stalin was a nasty piece of work, and yes, I can see this. But I can also see reasons why he did it. The gulags were unnecessary though, and the way he carried out his plans wasn't amazing. It had potential, but potential if it was carried out in a different way.
