Have we been reading the same story? This is very much in line with his personality. He takes no pleasure from killing, in fact, after a campaign he ends up puking, hating himself and calling himself a murderer. He gives someone he sees in need money and so long as it doesn't compromise the goal of the war, or atl doesn't seem to, he will rather live and let live.
He is a guilt ridden person that hates that he is taking any enjoyment from fighting, and hates himself even more the more he enjoys it.
