Am I in the wrong?

I am already telling you this is gonna be a long post. My best friend whom I met 5 years ago tried to "suicide" 3 years ago. Now, this was not from a tall building or anything just the rooftop of a duplex which wasn't even that high and would have resulted in her just being injured. This was because as she later told me due to her close friend's death that very same day. The friend who died had always had fragile health since the beginning and it worsened leading to her death. Our whole "friend" group went to her house because we were roaming around together when she made the excuse of wanting to change her dress and all that and went home. She reached earlier and rushed upstairs. We tried to come inside so she shrieked to not come inside and mujhe chhod do. We were all perplexed and rushed upstairs, to find that she wasn't on the first floor. We then suspected that she may be on the rooftop and so we went there to find her at the edge. She threatened us all by saying ki main ud jaungi and all. One of the girls in our friend group said ki "kud ja" as she already didn't like her all that well. She even tried to jump from another person's house which was beside her own. She didn't jump, and we managed to get her down. The days after that day were all a mess. Her mother called us all and talked to us about it. I always kept in contact with her while the others became a bit wary of her. She was a bit, "immature" as one might say but she was just 12. She slowly improved and worked on her betterment and became way better. We lost contact for a year and went our ways. But one day, I just dropped a message and initiated conversation again and we started talking again and have been doing so for a long time since. She has improved tremendously, and there is not even a hint of her old "immature" self. Now the things is I am moving out of the city and we are spending more time with each other, but my parents have been a bit wary of her ever since that incident. They always had a good impression of her but ever since that incident, it was all ruined. Even I added fuel to that fire along with my elder sister by calling her pagal and mentally ill. Now when we have re-established our friendship my parents are holding that same impression against her. They always tell me ki "uske saath akele mat ghumna", "kabhi vo firse kuch karde aur tere pe blame lagade to" and all that. They have not even met her properly since that incident but they are judging her. She has genuinely been really good, and I can tell that she has become way better but no one in my family is even giving her a chance. I am defending her but they are giving the same argument. Is it right to judge someone from their past self without even knowing their present self. Doesn't everybody deserve a second chance? You may think that I am being unreasonable but I can tell that she has become great and happy again. I don't even see a chance of her trying to do what she did again. Please tell if I am in the wrong in supporting her. I strongly believe almost everyone deserves a second chance and I have always given my friends a second chance.
