Not really true at all as by this logic mentally ill people who commit murder would be treated the same as everyone else but they are not.
It's also important because unless you understand why something happened you end up repeating it. Because of Ultron every potentially sentient AI was considered a threat to be destroyed and Aida inevitably rebelled against a world that marginalized her and sought her destruction.
It became a self fulfilling prophecy and will continue to be one until that attitude is changed. That's a classic conflict in man vs machine stories and it's pretty obvious here.
