Do you think I'm a psychopath?

Am I a psychopath. People called me a few times before. I don't care about anyone I mean id kill my own family and friends for any life changing amount of money. Id kill a random stranger for 10 bucks and if I could get away with it. I'd kill anyone actually for free if it didn't harm my life and I could get away with it. See I have a desire to kill someone. I don't care who they are I just to murder someone. I fantasize about killing people all the time. I don't care how but when i fantasize about it its always pretty gruesome. I'm 17 right now and I personally don't care if i am or not I'm just curious on what you guys think.
