Structure in Jude the Obscure

An interesting structural feature of Hardy's Jude the Obscure that I have just discovered, being half-way through the book:

1. Part first, chapter 2: helping animals (letting the birds feed on corn) - leading to problem (loss of job at farmer Troutham).

2. Part first, chapter 10: helping an animal (killing the pig quickly, instead of letting it bleed out) - leading to problem (Arabella gets mad at him).

3. Part fourth, chapter 2: helping an animal (killing the rabbit caught in a trap on the night of his aunt's funeral) - leading to problem (getting into a conversation with Sue at night and telling her that he'll give up his religious goals) - which then leads on to further problems (he loses even the small amount of motivation he had so far to resist his urge to be with Sue). 

The help Jude offers is quite ineffective in all cases, but it throws light on his compassionate and kind character. At the same time his acts of mercy symbolize that he is trespassing constraints: he ought not let the birds eat the farmer's crops, he ought to kill the pig in the best way for making money out of selling its meat, he ought to let the rabbit that someone else caught alone - the last one meaning the rabbit and Sue at the same time; Sue being caught in the marriage with Phillotson. A bad catch, so to say: the trap causes her much pain. But Jude ought no to interfere.

I do not yet know the outcome - I can make guesses. George Eliot's The Mill on the Floss keeps coming to my mind...Hardy depicts his characters in a similar way to Eliot as being driven to their fate by their passions. Both seem to point out at the same time the irrationality and pitiable lack of self-control of the character, while also criticizing social structures and institutions which do not give people like them the chance to fulfill their desires.

The fact that Jude's misfortunes are in parallel with his acts of mercy can also be interpreted as a criticism of lack of justice in the world. Those who follow the right moral principles will be frustrated in life because the dominant concept of what counts as rational, what is allowed does not leave room for the tender and gentle.
