I can so relate to your post OP. I can't tell you how many times I've actually wanted to become a vigilante serial killer like Dexter to take out all of the trash in this screwed up world and throw them in the ocean like he does so they can sleep with the fishies.

Unfortunately, it's getting much harder to get away with murder due to advances in forensics

In fact, literally the only thing stopping me is my fear of spending the rest of my life in prison.

There is absolutely nothing wrong with what you're thinking. Don't let anybody tell you otherwise
