Sad to think that he just wanted to kill anyone whom he came upon :9. Do you think that he may have wanted to die in a "suicide by cop" scenario? He sure was giving the police more reasons to shoot him when they came upon him, he must have known he couldn't get away with such a dastardly deed. He was a madman through and through. Glad he's dead ( Sadly that won't bring his victims back) and not going to serve time in prison with 3 square meals a day. JMO
Once his initial targets were killed( likely people he had some kind of previous contact with) he then appears to just had wanted to cause as much chaos and carnage as possible. Whether he had planned to be killed or commit suicide himself, we will likely never know. One thing for sure, he needed to be stopped and stopped quickly bc the longer it went the more lives that were going to be taken.
