Should people be judged for their past: No
Will people be judged for their past: Yes
Judging is something that everyone does. Even here on Sythe people judge each other about everyday. Which person will get the trade? The new person or the person with 120 vouches.
Judging may be unfair to some people. If you had a bad past and you apply for a job, you have a faltered chance at getting it, even if you swear to have changed. Because if the next person that comes along that has done better than he will get the job.
