I didn't say this guy should be let free. But I do believe that the broken penal system is in the dark ages and needs to get with rehabilitation (for those capable and willing to be rehabilitated). A side note to our backwards penal system is those in prison should be put to productive work at least helping to pay for their room and board.
Sorry mate, but operating a penal system on the basis that criminals will find Jesus and repent their sins is impractical and open to abuse. Some people need to be able to appreciate the consequence of their actions in the here and now, not just the hereafter. And whilst forgiveness by God is one thing, it doesn’t negate the need for people to be punished for their crimes in this world. Anything less is a recipe for anarchy if nothing else, and anyone who is truly repentant would accept the earthly consequences of their actions with good grace, rather than simply arrogantly assume that everyone else should just let it go because they claim to have found religion.
