Ok, but that’s not what your earlier comment said. It’s quite the opposite of your earlier comment.
Anyway, even if we do take it that way, as others have said, it just doesn’t work that way. Keeping these secrets is enabling more deaths to occur. The “fucked up secret” was “people are getting away with murdering noncombatants and prisoners and covering it up”. By revealing this “fucked up secret”, McBride was helping to save lives.
Ironically, this is kinda what you seemed to be acknowledging in your earlier comment. You said that keeping the secret leads to deaths (“keep a fucked up secret then have 10 men die”).
