Seeing As He's Apart Of The Guard, Has Saldamek Ever Encountered Xenos Before, Or Has He Only Fought Against Chaos? Does He Have The Same 'Purge The Xenos' Belief That The Rest Of The Imperium Has? Or Does He Try And Make Good With Any Non-Human?
His love and grace doesnt extend that far...
Empathy is something he learned to accomodate for and serve an innate affection he harbored for mankind since his birth, Xenos are not his kind, and matter of fact most of them actively seek to harm his kind, so no mercy in that regard.
(Heh heh, a yandere for his own speicies)
Thats not to say he CANT learn, im sure he can, given he's put in the right situation, hell it might serve his character growth well, but it WILL be a difficult journey
