As you said none of us here are professionals but I will say that I can relate to several parts of your post. What you wrote about your childhood reminds me of mine in some respects. I started mimicking what was seen as "normal" and I also lied like crazy just for the sheer flipping hell of it.

I don't suffer from boredom to the same extent as some others with ASPD but I can still relate to being motivated by boredom. I've engaged in many antisocial antics out of boredom and nothing else.

I had homicidal thoughts very frequently when I was a teenager and young adult. It's faded off for the most part now, thoughts like that float through my mind on occasion but it's not a problem for me.

I've never felt guilt/remorse for anything I've done, even if I pretend otherwise out of necessity.

I think at the least you have some antisocial traits, it's hard to tell just over the internet but that is my non professional opinion.
