No I disagree, I just reread Chapter 65 again and Old Man Ackerman is telling Kenny that the vast majority of humans inside of the walls are of a single bloodline (aka race). Today we saw how Reiner harshly chastised Annie for risking her life to save someone he regarded as an 'evil race' and a 'defiled race'.

We don't know the whole story, especially what exactly he means when he says 'defiled' and 'evil' but you say he doesn't like to kill people and regardless of whether he enjoys killing people, he does kill the people within the walls with some conviction because he appears to see them as a kind of human that deserves it in some way and in some contexts (when it suits his objectives). It's Bertolt who seems guilt-stricken.
