The official version is that, after being aware of what was exactly going on in Auschwitz in mid 1944 (see my post above), Churchill ordered the preparation of a bomb raid, but finaly cancelled it when the deportation from Hungaria ceased.
The risk of multiplication of gas chambers like syphillis in the clergy or killing inmates never weighted in the debate.
Anyway, as i posted above, if the Allies had bombed Auschwitz there would be as much debate about why they did as there are debate now about why they didn't
