He's a Father through and through - no actual apology, no real acknowledgement of the pain they caused Friday, just more excuses. It doesn't matter that they hurt Friday first, only that Siffleur finished the fight in away that Crichton finds disgusting. There is no reasoning with a man like Crichton, for he will always shift the goal posts.

He tips his head up, looking Crichton in the eye, and makes him a promise.

"If we escape, I will find a way to visit another universe where your mother is alive, and I will woo her, and I will give her a son she can be proud of."

Then he gets the fuck out of Crichton's face like he wants.
