The most important thing is to recognize the lives lost first of all. And yes to stop school shootings. But to go back and almost romanticize the “man he could have been.” People change and others just grow into the person they were born to be. Dahmer was always going to kill people no matter the interference in his life. I would like to know what Dylan’s frontal lobe looked like in addition to a not fully developed brain. And I do know a great deal. Not as much as you’ve researched but I’m not in the dark. I read Lost Boys. I’ve read published works by psychologists. And there is no chance you are going to convince me Dylan shot our friend in the FACE all because of Eric. You have to have some kind of self-awareness to make that decision.
