The Bolsheviks understood that simple wealth redistribution wouldn't work....the rich would get all their money back within a few short years, so nothing would change....therefore the only way to achieve the change would be to simply murder them en masse. Deep down all true Communists believe that this is the only to bring about the Revolution, they will deny it, but they all truly think that way.
Funny or sad thing is it was the university students that started the whole thing. It wasn’t the workers. It was rich students who started the protesting of the Tsar thing.
