I don't think it's possible to look at these sorts of things "objectively" and I don't see much point in even trying.
Neither do I. But sometimes one feels so much hatred and anger that the sane part of one's mind will be very aware of the fact that it is probably better to wait until one will calm down (which may take months) and then make an opinion. Of course, sometimes you need to form opinion quickly, but that is not my case right now.
It is like when someone makes you very very angry and you want to hit him in his face. You will be aware of the fact that it's maybe better to not do the thing, to calm down and then evaluate situation again. But it depends. Sometimes you will decide to hit him. This time I decided to calm down.
(And also, sometimes when there is too of painful things in one's mind something will happen [there are more possibilities what exactly] and then there is no more any pain, no nothing. Just emptiness. (Usually only temporary:) This makes forming an opinion quite a hard either.)
