Hmm…would he be spoiled? Bored maybe?
Yes, it is hard to speculate... but I'd rather think of him being spoiled. People like Dolokhov would literally die if bored (for example got ill). They can't survive without constant actions. I don't think that Onegin and Dolokhov share the same personality type.
Ironic, sort of, because Dolokhov was really playing the traitor here: Nicholai already was “with” Sonya.
That's true. But he didn't see that or should I say he would never admit. Surely he is an egocentric type.
And yes, maybe a bad expirience has caused such a suspiciousness.
