Finn and Rose's well-intended quest results in
a code breaker being brought to The First Order who makes a deal and reveals technology used by The Resistance.
It seems a very ironic consequence; had they not departed,
The remaining Resistance would have likely escaped.
As such, wouldn't the responsibility for The First Order's
decimation of The Resistance and Luke's sacrificial death
ultimately fall on these two and their actions? Is this addressed in the movie or perhaps mentioned by the directors as a potential long-term psychological consequence for the characters?
