[Lenin] was an able suppressor of outward emotion. He acted calmly even after the trauma he suffered when his elder brother Alexander was hanged; and later he was to find steady satisfaction in his work alongside his wife...There was always the possibility of an explosion:Lenin was a human time-bomb. His intellectual influences thrust him towards Revolution and his inner rage made this impulse frentic. Lenin had a greater passion for destruction than love for the proletariat. His personality is closely linked to the kind of politician he became. His angry outbursts were legendary throughout the party before 1917; shortly before he died they became so acute that serious questions arose about his mental equilibrium, even his sanity. But usually he took a grip on himself and channelled his anger into a controlled form of agression. He was a political warrior.
