The first sentence kinda captures the ethos of the Emancipation of Labor Group, the first Russian Marxists - whom Lenin eventually joined. They were critical of the then dominant People's Will, a leftist terrorist movement that thought the only path to revolution was to bomb and assassinate as many bureaucrats, capitalists, and royals as possible. But, of course, the didn't eschew violence altogether.

The second sentence is revisionist Marxism ala Eduard Bernstein, rejected by the vast majority of Marxists, never would have left Marx's lips.
