Why would we want to? Perhaps because there will be a rebirth? (Assuming we are speaking figuratively.)
I think you have to judge, not in a juridical sense, but in a more basic sense. Judge if others are trying to take advantage of you, when they are trying to take advantage of you. You don't have to look over your shoulder for exploitation. You will find it face to face, and that's where you should be ready for it. It's hard at first to stand up for yourself, but it does get easier in time. Remember - you don't owe an exploiter anything. You really don't.
How U know U can Judge ?
Knowledge can be a form of judgment.
Re: Are you too nice?
Some people are too passive and some people are too aggressive but only the wisest can attain the perfect balance of the passive aggressive.
