What does someone like Tyrion think about capital punishment for things like defecting from the Night's Watch? In fact, at the start of the series when everyone thinks the worst threat beyond the Wall is the Wildlings, how can they even justify death as a reasonable punishment for defecting? The whole system is stupid.
Most of the Wall is a glorified prison camp where criminals go to get out of society's way. Think of it as the medieval fantasy equivalent of picking up trash along the freeway. If one of them tried escaping they'd likely be punished too. Of course, the most simple punishment at the time was lopping a head off. It makes sense if you think about it at all.

No one wants to serve in the night's watch
If they took deserters lightly everyone would just run off
