What are some similarities in characterization between Tchichikov in Dead Souls and Bazarov in Turgenev's Father and Sons?

While there are more differences between Turgenev's
Bazarov and Gogol's Tchitchikoff, there are certainly similarities, especially in the
social ramifications of their behavior. Both Bazarov and Tchitchikoff manipulate other
people for their own purposes, though their purposes are unalike. Bazarov manipulates
the ideas and allegiances of younger students, who look up to him, in order to feel
superior and accumulate nihilistic followers. Tchitchikoff manipulates landowners--serfs
in Russia were always attached to the land, so landowners were by definition serf
owners--in order to increase his wealth by his serf purchase scheme. Each callously left
behind a trail of victims of their manipulations; neither set of manipulated people
necessarily felt the manipulation while it was on
going.

Both men were visitors imposing upon hosts'
hospitality and neither could find legitimate sincere attachment from a beloved. Bazarov
was rejected and Tchitchikoff was perpetrating fraud. Both lived determinedly by their
own codes instead of by society's code of behavior. As a result of these things, both
Bazarov and Tchitchikoff alienated other people. Finally, both were punished in the end
for the attitudes they held toward society, toward the worthiness of other people, and
their role in society. Bazarov accidentally infected himself with typhus and died.
Tchitchikoff was discovered in his attempt at fraud and
imprisoned.
