The tree analogy is solved by the way a person defines 'sound'. If a person defines sound as a physical event including soundwaves, then the person will argue there needs to be no listener for there to be sound. If a person regards 'sound' as a listerener's experience, then the person will argue the tree made no sound without a listener.

For me 'evil' actions are harmful ones with the intent to harm. I do not see the legal comparison as truly relevant. Yes, plenty of psychopaths dabble in the illegal, but not all. You wondered yourself though the impact of your disorder within your personal relations. So, the question remains whether you are at the very least 'harmful', even if not 'evil' to those personally connected to you.

I draw the line in who I allow in my life based on them being harmful or not. I cut and shut out friends who have done me harm by their actions even if those actions were prompted by their loving intentions. But at least I think the only one who has the right to mess up my life is me, no one else. No, they are not bad, or evil, or criminals. I do not look down on them. But they are harmful, because they either do not recognize boundaries or do not respect them, and I feel I have the right to protect my life from harm and my boundaries.
