That's one view.
The other is that prisons are for correction and rehabilitation.
And there's a myth about prison right there. Spoken by someone who clearly has no idea how horrible prisons really are. And how dangerous and deadly they are for anyone even accused of offenses against children.
He shouldn't live, period: he should go straight from the jail where he was waiting trial, to the gallows. Prison should be for those who are bad enough to remove from society for a time, but not bad enough to execute; and since they will be returned to society, we should try to make sure that when they re-enter it they do so as productive, mentally-well members of society, rather than as beaten, brutalised future recidivists.
But not the moral implications of keeping someone caged like an animal for the remainder of his life. What's worse: to die in a week, or to spend decades in prison?
I bet if televised, public executions would be the biggest PPV draw in Oklahoma and Kansas. It could fund schools, lower taxes, and most importantly, fund bigger gallows for executing more of the people we decide shouldn't live anymore.
