One may "feel" for M - though a man who, in the 21st century, marries and "begets" children while knowing that he really loves (?) - or, rather, lusts for - men is, perhaps, not very likeable. But as other commentators write: one cannot but hate M's mother, despise his father, and feel that both Andre and Ryan are less than upright men. So that leaves Sarah and the poor twins; in the end, they are the ones who will remain shattered For, inevitably, M cannot see "the light". He is gay, and unless his family, perhaps, accepts that, the pain is theirs, mostly.
