I've read versions of the story that report Gallagher to be exactly as the prosecution described him.
Trump stuck up for him, but, without knowing the truth... the actual truth... I think it's correct to say that Crenshaw said one thing and did another, but, what facts became known to Crenshaw later?
Yes, NY Times, I know... but the source was from the trial proceedings/investigations.

After the verdicts, sentence and pardon, the New York Times revisited the case and accessed, using the Freedom of Information Act (FOIA), investigative reports and also videos of interviews in which six SEALs under the command of Gallagher had separately extensively detailed his ongoing prohibited combat zone behavior, sometimes crying as they recounted the abuse.[54] "The guy is freaking evil," Special Operator First (SO1) Class Craig Miller said. "The guy was toxic," said SO1 Joshua Vriens.[54] Special Operator First Class Corey Scott, a platoon medic, had informed investigators, "You could tell he was perfectly O.K. with killing anybody that was moving," but recanting his testimony during the Gallagher trial, for which he was given immunity,[31] saying he had committed the murder himself, presumably powerfully influencing the verdicts.[54]
