I'm all for it in cases like that, but there needs to be some type of psychological testing and probably a time period where they see if the person has at all started to feel regret or guilt.
A good example is Jeffrey Dahmer(Jeffrey Dahmer - Serial Killer and Cannibal - The Crime library
). What he did was inexcusable and he should've been sentenced to death(not 15 consecutive life term, which is ridiculous in my opinion anyways -_-; ). I think he was a calculating... inappropriate word... that was only playing the court by claiming remorse. I'm certain a psychologist would've proven that his letter of apology was just an attempt to wiggle out of his crimes. I suppose I'm thankful he was killed by another prisoner.
