Apparently, the wholesale jew killing business is more complicated than we thought. Perhaps the camp commander was thinking about how he would be judged in the future. You see, as we now know, according to jew rules, until it actually passes through the birth canal and is seperated from the mother, the "parasitic mass of tissue" isn't really a whole jew yet. If the "birthing parent" were to be executed with the "parasitic mass of tissue" still inside of she/her/he/him/it, that would only have been counted as "one jew killed" towards the camp's tally of total jews killed for that year. That's exactly the kind of number that can end up on an officer's efficiency report. So in order to have an accurate count of total jews killed, they have to be born first. Then killed. So they'll all count towards the total number of "jews killed". See?
