I believe Robbie's problem started at an early age cause of problems at home. I honestly don't believe that step-mom. I think she made it just as hard for Robbie to live in that house. Yes, he ended up being a mass shooter but it's so easy for her now to paint herself as a victim from the time that boy was a toddler in order to shift blame from being part of the reason that boy turned out the way he did. From the time he was young she never wanted that kid. I am sorry but no real birth mother would ever send their 4 year old child to an institution and walk away so that he can get the "help" that he needs. No a birth mother would send their child to see a psychiatrist for a weekly session and bring them home. Poor Robbie abandoned at an institution at 4 years old. God knows what they did to that boy. She also claimed she doesn't know what happened while he was there. Wow just wow ! That kid would have been so confused and felt alone and unwanted. To make matters worse the step-mom claims she doesn't remember how long he stayed there the first time. This boy spent most of his life in institutions from the time he was 4 to 17 years old than in his own home. That right there shows me the level of care she had for that boy..... zero. This boy was failed by his father and step-monster from the very beginning. Also her begging her husband to kick out the boy wow! She also refused for him to come back even for visits and gave her husband the ultimatum that if he comes, she goes. This woman is horrid. I believe a series of events brought about by the dynamics in his family led to his spiralling out of control cause how many times can you handle being told and shown that you are not wanted. Sure the boy was no saint but I believe his behavior and actions where a reflection and the result of the turmoil that was going on in that house! He was so far gone! I feel sorry for his victims but he was also a victim too !
