I don't think any of these are immoral except for the death penalty.
I see that the bizarre idea that life imprisonment is somehow the same as the death penalty has crept in here. Is this the latest fuzzy liberal thinking on "rehabilitation"?
I find the idea that a person should be kept in for life without the possibility of parole to be immoral. Anyone should be eligible for parole at some point, with only those still truly dangerous to society kept locked up.
FTR, my views on most of these are fairly nuanced, though I would only call a few activities on here "immoral" (the death penalty being one of them).
