Gone
your point seems to be that the flatmates had a certain set of beliefs and emotions about abortion and therefore we are not entitled to judge them as they were only being true to themselves.
I was raised to be kind to those in trouble, to think "there but for the grace of god go I" when people are struggling, to think the sermon on the mount is an accurate description of how to live a good life (Did you "shop me to the police when I committed a crime" isn't included strangely enough) and to dislike people who seek vengeance (I had lovely kind christian parents) so I also have a set of beliefs and emotions and mine tell me these flatmates are nasty, vindictive, self-satisfied, and mean-spirited. Whitened sepulcres as it were. I know many many people who are not pro-choice but would still not have reported this girl because they have essential human decency which these 2 flatmates clearly lack, You'll be fine with me saying all this because these are MY beliefs and I am entitled to them.
I have had a miscarriage at 12 weeks. There wasn't a victim, I didn't have a baby and I didn't have to dispose of a body. The language you use which sounds like a crime novel (disposing of the body!) tells a lot about your attitudes.
