Because at first you have to find the cause of the behavior. Punitive justice should be the last resort. The problem, the moment justice has to work, a problem was not discovered and solved early enough. I would say every government punishment is a prove about a community and government failure. The moment justice step in you need to punish an incorrect behavior to prove that the rules that exist are valid and enforced. So one part of the punishment is not for the criminal it is for strengthen the existing rules.

In developed countries there should not only be the punishment but also an investigation how this could happen and some form of help to solve the issue. And additional punishment if other people where harmed.
