Is there a correlation between online and offline vandalism? I did some searching but I was not able to find anything substantial on this topic either for or against. I am mainly trying to figure out whether online trolling is a way of redirecting otherwise destructive offline behavior.

So, is there a correlation between online vandalism (trolling) and offline vandalism (damaging/defacing public property)?
According to this study, there really is a correlation:

  The research, conducted by Erin Buckels of the University of Manitoba
  and two colleagues, sought to directly investigate whether people who
  engage in trolling are characterized by personality traits that fall
  in the so-called Dark Tetrad: Machiavellianism (willingness to
  manipulate and deceive others), narcissism (egotism and
  self-obsession), psychopathy (the lack of remorse and empathy), and
  sadism (pleasure in the suffering of others).
  
  It is hard to overplay the results: The study found correlations,
  sometimes quite significant, between these traits and trolling
  behavior. What’s more, it also found a relationship between all Dark
  Tetrad traits (except for narcissism) and the overall time that an
  individual spent, per day, commenting on the Internet.
