LUHE I think the death penalty should be kept
The problem with any punishment is, that callous criminals will commit murder, worse crimes, to keep hiding their identity, escape punishment.
maybe, that is why Cain was never punished, the not so good samaritan, that knew about the plan never intervened. in the genesis story. --- good samaritan laws now?
btw, people have been executed for being just part of the party that was involved in a killing.
