What sort of sick mind would starve her own 3-years old child to 7 kg and make him undergo several unnecessary medical treatments and hospitalizations? Sick or criminal? Whatever the answer, when a child is abused in his own home, he is left without a safe harbor, he ventures into the world without a base camp. What kind of life is that when you can't trust anyone and don't have a refuge? Will he be able to have a normal life as an adult? To establish his own family and provide a safe environment for it? I guess it depends on your age when something like this happens and the help you get. He is still young, he can make it. I hope.
Former Israeli TV rating king Dudu Topaz grew up in a normal family and made it to unprecedented stardom, but ended up hanging himself in prison after ordering attacks on influential TV people who wouldn't hire him anymore. He could have done a million good things with the money and time he had, but he perceived himself worthless without audience adoration and that affected his psyche and acts. He lost his internal compass and got addicted to liking by others until his self definition became completely dependant on external rewards. Sick or criminal? In this case, it doesn't really matter anymore.
