Or maybe you’re just wishing for them to have a conscience - which may be too much to wish for too.
It's worse than that. They might have a conscience and feel bad. What I am hoping for isn't just "feel bad," I am wishing for torment, enduring mental hell, inability to escape the pang, consumed by guilt.
A Christian thought would be that they find forgiveness, and are relieved (somewhat) from the torment that I want them to experience.
