Judging someone by their past will never allow you to know them in the PRESENT!
WE ALL HAVE A PAST - for the most part we do. WE ALL HAVE SOMETHING or THINGS we have done that we are not proud of. Or things we wish we have done differently. Or maybe we have done things that we do not REGRET, but also do not feel the need to be reminded of because we have changed and have a better sense of RIGHT from WRONG. I think when it comes to passing judgement on a person, the best stance to take is to see the situation from every angle. There is always more to the situation than they there seems to be.
