Kip had no right to take their lives away. However people forget to think about Kip. In some situations, such as I feel this one was, Kipp deep down is a good person. I have dealt with many people who have similar psychological problems as the ones Kip have, and it makes it a little easier to understand WHY he did what he did, but in no means do I mean that it makes what he did okay. What he did was undescribingly wrong, but I couldn't imagine what it would be like to live a day in his shoes, with what he was going through.
People often underestimate that horrors of psychological illnesses.
Of coarse even if it is his diseases that were mainly responsible for his actions, and he is capable of functioning in society, the risk really is too high. After looking at all of the information available, there is no doubt in my mind that Kip had serious psychological problems. Although I do not believe that he was psychotic or schizoprhenic, in the clinical sense. It would appear that his pattern of behavior before, during and afterword, suggested intact cognition. Most likely it would have been an uphill battle to convince a judge or jury of Kip's inability to understand right from wrong, or the consequences of his actions.
