I disagree with the premise of your question. It is quite a philisophical can of worms. I do not think anything is "supposed" to be like anything. But then by me saying that, it could mean that my answer to your question is yes. Because things are what they are because there is no game plan and things happen randomly. That's not to say that I agree with the bad things, just that I don't think there is any preconceived plan.

If some say to that...."how do you know right from wrong then?"...there is a simple litmus test. Do unto others, etc. I'm not religious but that rule is a basic of humanity...even if it's not practiced as much as it's preached.
