What's the most immoral thing you've done in Skyrim?

I'll start. In Rorikstead, you'll find the family of the abusive widower Lemkil and his twin daughters Britte and Sissel. Britte is a little bastard who spends practically every waking moment bullying poor Sissel. I came across this dysfunctional trio by chance before I found out that you can make certain children available to adopt by (ahem) removing their parents. I found this out when on one playthrough, I was in Rorikstead the first time Mirak's cultists came to start trouble. Lemkil was killed in the scuffle by no fault of my own. I didn't think about it again until I went to the orphanage and found Britte and Sissel there. The thing is, I'd already adopted Lucia in Whiterun, so I could only adopt one of the sisters. I adopted the bastard Britte and left sweet Sissel in the orphanage.
