He saved Omega anyway at the end of season 1 and nothing forced him to.
The "consider us even" is an excuse to save her.
He could have abandoned Mayday, why save him ?
He was not obliged to warn Lot of the danger he risked, why help them?
He could have said everything he had about the Batch but he didn't say anything even under torture.
And when he turns against the Empire (Nolan), he looks terribly touched.
He says to himself, no shit, I'm no longer of any use to them, he really seems to have lost his purpose.
He saw himself as nothing other than a loyal and obedient soldier who was faithful to the regime of the Empire.
In fact, in season 1, under the influence of the chip, he looked like a psychopath.
But we see a big change in behavior afterwards.
And even Dee Bradley never implied that Crosshair was of this nature.
