I think this is the problem of most people who believe in God. Some of them do not understand that it is humans that allow such things to happen. We can always have a choice on how things can happen. The moment we wake up until the time we sleep, all of our actions the whole day is being decided by us.
Just like rape and murder, it occurs because all of us allow it to happen. I am not saying that these victims are dumb. But we try to analyze things, the people around these criminals has their own share of obligation too, like the police, the parents, the neighbors and so on. Although it may be case to case basis, the victims somehow had the chance to kill these ruthless criminals before they got killed but for whatever reason, they do not have the guts.
Pls. do not get me wrong. I pity the victims and their relatives and friends, but for me a crime should be prevented by all of us. That is, if all of us are working hard about it including the parents of potential criminals, then maybe just maybe our only problem will be pride and money.
Lastly, I believe in God although I may be looking the other way.
