self-righteous (hypocritically . . . ) adj.: Pharisaical
[This is derived from the Pharisees, an ancient Jewish sect].
What a dreadful thing, that a mother was so poor that she was inclined to abort one of her children. Couldn’t she be helped? The pro-abortion people [muttered]that it was an outrageous breach of medical confidentiality that the story should come out at all: a somewhat Pharisaical comment in the light of skillful media manipulation from the same sources when the case suited them. (Mary Kenny, “Death before Birth,” National Review, 9/30/1996.)
