Judgement

I've been asking myself this question "Who are we to judge others?" so far have not been able to find a good answer to this question. When we say others are bad, we are looking at them from our own eyes our own perspective, wat makes we think we are almighty? wat makes we think that the things that we saw is the truth, wat makes we think that the views we pass on others is unbiased? Wat makes we think that the things tat we feel wrong is really wrong?
Nothing in this world is perfect and that includes us. We always heard people mentioned "you don't understand cos you are not in my shoe". Of cos this statement is not entirely wrong but ask yourself this "Do u think that you have to be blasted by a atomic bomb to know that a atomic bomb blast is powerful and destructive"? this is wat my primary sch chinese teacher told me, and I think it's very true. there are some things that are not that complicated and some that are. We can't always assume that other people don't understand our plight just because they have a different opinion from us or the sided with the other side. Now then I am not saying that this is very subjective I am not saying that I am right, I may be wrong also but this is wat I feel. Sometimes people are really so heated up that they can't see things from other viewpoint, they only look at it in their own small angle, in this case they can't see the whole truth.
