In what way does Helena's statement that Jimmy would feel more comfortable with things during the French Revolution sum up Jimmy as a person?

Since he has no revolution to fight, he makes one wherever he can find one, thus alienating his friends and family and ending up right where he started. This may be where much of his frustration is coming from: he was born out of his time, and finding a completely inert society around him, he is left with no outlet for his revolutionary tendencies.
