Andy, while I am not necessarily "all for it", I can see how im some exceptional circumstances, where somebody can't be rehabbed, it may be the more humane option (not necessarily here, as I'm not convinced he was even sane). But locking someone in a cage for life, is hardly a sign of "civilised" society either. And particularly so, if they either didn't know what they were doing, or couldn't help themselves, genuinely.
My first sentence was purely to say it isn't "murder" and that i don't think using emotive words, instead of accurate ones, is a fair debate.
