Am I a sociopath or sadist? And is it possible to be both?

I am 14 and a Pathological lier and I am almost incapable of telling the entire truth unless it is to my advantage. I hate showing emotion and shove it away when I can. I can't get work done in time, because I just don't think it's important. I can change my personality in the blink of an eye if the situation needs it, so that I can have the upper hand. I am very secretive and paranoid. I show little to know empathy for people. I spend huge amounts of time everyday fantasizing of hurting people. I get enjoyment from humiliating and hurting people, even my close friends. I am obsessed with the themes of torture, murder, weapons, induries, and fighting. Although I do love violence espiAcially towards people. But I do not like hurting animals very much, like my dog. I have never tortured an animal for fun because they don't have the feelings as people and they just don't deserve it. this is probably cause I grew up with animals all my life. I am very interested in and forced ual acts. I carry knives with me everywhere because of paranoia and hoping that I can use it. I've come up with several working murder schemes all with ways to get rid of evidence, but I havnt acted out on these... Yet. I don't kill people because it's illegal and I do not want to pay the consequences. If it was legal I would kill all the time and love it. I think I'm a sadist but I lack the impoliteness, probably cause I'm so good at hiding it. I also have strong beliefs that I am a sociopath. I asked this to confirm my beliefs I am not looking for help. Plz answer!
