can only echo hammermans sentiments, hard labour with serving your sentence right upto the last day ie 10years no ''GOOD BOY BEHAVIOUR'' reduction in sentence, no TV, playstations and other perks.
Give them nothing, other than plenty of THINK TIME to realise why they were put behind bars in the 1st place, at present its Butlins behind bars.
Even tho i agree with certain exceptions for the Death penalty, This is not a deterant, it would be an easy way out for thos who commit the most horrendous of crimes, and it WOULD'NT reduce Murders & Rapist & Pedeophiles, just see what goes on still in the USA with crimes and Death penaltys, not much of a reduction you will notice.
i would like to see sentences like for example,
The judge says to a pedeo who molested a child, you will serve 15 years hard labour, with no chance of remission, no perks etc like TV's & Radios, and at the end of your sentence, i'll let you know, if the child who you molested is in a forgiving mood otherwise your stay behind bars until they decide to forgive you.
It MIGHT just register with some of these pedeos/Seriel killers etc in their brains before they commit these horrendous crimes, tho i would'nt hold your breath
