Does anyone else enjoy being a psychopath?

I relish in being a psychopath. Although I'm great at manipulating others into doing favors for me (I'd say I'm decently attractive and give off a very polished, driven personality), I very rarely feel appreciation for anyone in my life. I attribute much of my success in life to this, especially throughout high school and college when I've relied on others' help to climb to the top of organizations, only to then cut them out of my life when I saw no further use to them. As such, networking, dating, you name it, have always come easily to me. Yet this mindset also extends to my relationships: I am quite mercurial to the people closest to me, in that my friendships and relationships are very untenable, and someone who may see me as a friend I see as merely transactional, and am ready to cut them out of my life if they do something I interpret as disrespectful to my ego.

However, just today I was speaking with my parents, and they told me they had recently reconnected with a parent of one of my childhood friends. He and his family did huge favors for me back in middle school, and I remember how I eventually cut off ties with him in high school because I didn't see any use in his friendship. Remembering him, I felt a tiny tremor of remorse; this was a friendship that began in my childhood, before I became so toxic and so laser-focused on success. However this feeling faded as quickly as it appeared--though I still felt compelled enough to write this post. So to all you psychopaths working on the Street, how have you maintained this mindset at all, especially if you enjoy being a psychopath? Has it helped you climb the ranks at work? Or did you eventually come to terms with it? Thanks.
