How about they make it illgal to employ girls this young in the home?? That would be one thing. Charge this murderer and execute him too.
Not going to happen. This is a mostly Muslim country. The Christians are poor, and kept down by the government, in a semi-official manner.
The only two things that can be done in such a situation is to either resist, or become slaves. If you resist, it means you must employ eye for an eye, or worse violence. You still maintain the upper hand, if the violence is only directed at the criminals.
The idea is not to maintain the status quo, but to teach the oppressors to stop oppressing, or face possible consequences for their actions. Since most such people are cowardly bullies, when met with resistance, they tend to back off.
