The Problem With Remorse

 Adults who feel remorse don't feel remorse, because they think ahead and don't do the thing they'll regret in the first place. 

 Children get a pass since they have great difficulty thinking ahead. I suspect non-abused teenagers are already too old for this pass. 

 Adults who do things which ought to make them feel remorse are shameless deviants. If they had the capacity to feel any form of guilt, they wouldn't be doing it in the first place. If you need to demand an apology from an adult, demand instead their life. It would be the merciful and compassionate option, since they a) they clearly hate themselves and b) all their neighbours would be better off without them.

 Consequently remorse is useless. Consider children again - remorse only works if you can think ahead, and for the purposes of this discussion, if they can think ahead, they're not children. Meaningless suffering. Adults, at least adults who know what words mean and have the capacity to feel remorse, can simply be asked not to do whatever it is. They can be reasoned with, and don't need to be forced, even by internal factors. 

 Completely useless.
