Angels, Do they really protect? Options

Hi all... I did not know on which forum to post this topic and i hope its not a problem putting it here...
Well I've read that everyone has 2 angels with him/her... One the guardian angel who accompanies us in all incarnations etc.. and the normal angel who is with us for this particular incarnation...
Then if any person has 2 angels with him/her and above that there are archangels/Principalities/Virtues/Powers/Dominions/Thrones/Cherubim/Seraphim who are here to protect humanity, then how come sometimes there are extreme crimes being committed to innocent people... the crime i hate most is rape... Could someone elaborate on when are the angels supposed to interfere... Rape is a case where i think even satan could come to the rescue if called upon...This statement is to show how much i condemn such a crime....
Any body can enlighten me on why such crimes get committed without the interference of those who have to protect us?

Well this question may seem silly,but i need to lean a lots on the functioning of this world...

I don't think it's all controlled - what would be the point? The closest comparable situation I could use as an example would not be a liked one - imagine that you're running a roleplaying game, and you make two of the non-player characters, that you've put a ton of detail into, fall in love. The whole thing seems utterly pointless.

this part i agree too in respect to what i have come to learn... I think that Humans are the creature God really likes and made resembling himself... I also have come to realise that God also has given us a mind and sub concious that can be used independent of him.. i.e we are free to choose and path we want. we are free to do bad but for every bad wee do, there will be a consequence to that... well till now its what i have been able to grasp..
------------------------------------
the concept of incarnations etc is somehow a bit complicated to me... The soul has been created by god and has to go through several incarnations to acquire knowledge and to finally become knowing of everthing and even being able to acquiring all that one may wish to such a point that the soul no longer need to re-incarnate.... then the soul will merge with the supreme being...I dont know what happens next but from a book, i ve read that the merging is done to serve humanity and the world better in a "multithreaded" way... But serving humanity would be like to aid the process of soul incarnation and reincarnation etc.. it will be like someone going round a tree and when he has made a lot if turns, he helps another person to make the rounds.... I dont find a real aim at this.. IS this concept right??? I dont think so ...
If it is right the this concept serves as a backbone for humans to take birth and experience life.... it also serves to build people different from each other so that we dont ressemble robots made in in assembly...

However Theres something else, If Humans are made of The supreme's being appearance and powers etc, then is it humans who are the most powerful creatures of the universe, is that right? even if we are not really aware of all powers we can have... But this can also be the case that Creatures from other planets can be in the form of God, that is resembling us to a great extent of what we will look like thousands of years later.. I read from a book that one person was made to do astral travel through the universe by super advanced creatures but finally what the person found that in other planets, there were some creatures resembling us to a great extent.

Any opinions on this matter that i have tried to derive from what i am learning...
