Sounds oddly heroic yet dark in a "the hero riding a horse to an uncertain fate" kind of way, which makes sense as the character has still some happiness but is gradually losing it, and the scale used here kind of gives me off a spanish vibe.
But yeah, that final part really sets the mood for the story you described, if anything I would associate that cresendo at the end combined with the intense percussion and trumpets to a desire of revenge, or plainly very intense rage and hatred on top of the sadness from right after the gunshot.
