If it's completely Ok for a God to allow suffering and evil for a person's growth or perfection then it should be perfectly OK for humans to hurt other humans and cause them to suffer since it leads to their growth or perfection and it's also perfectly OK to watch some act of evil occur or allow someone to suffer, since we're being following God's will and allowing that evil or suffering to make that person better. In fact it would actually be evil for any human to stop another human from committing an act of evil since it would interference with the free will of the one perpetrating the act (which is evil) and also it would interfere with the growth or development of the victim of the act of evil, so I guess no need for police or prisons or anything, people should be free to do whatever they want without consequence since interfering with people's free will is evil, freedom for all and no one has any moral obligation to stop any evil or suffering, since it would be a bad thing.
