In principal, I'm against it, and don't think it's logical to commit the same action on someone for which they're being punished for, alongside the other obvious problems with it.
I'll say I'm a bit flexible though...and acknowledge there are some cases where rehabiliation is impossible and/or keeping them alive is a severe detriment. I just find those cases to be exceptions for the most part.
