Is it normal i might be a psychopath?

I've been reading online and display mostly all traits of a psychopath. I've been studying it for a long time now, and have often questioned if I was one.

I generally mimic people around me and put on a different facade to who I really am. I lack empathy and occasionally have urges to kill people, even if they've done something minor such as something I find irritating or if they pester me when I wish to be alone. I also enjoy manipulating people emotionally, and I don't like following rules.

The thing is that I DO have emotions, however they are rather minor. I am confused at this as studies have shown psychopathic people do not hold true attachments to people and feel no emotion at all.

I do have an attachment however, to one of my closest friends. I am overprotective of them even if I may not show it, and when someone were to perhaps wrong my friend I feel like they should be slaughtered by my hands.

That's really the only attachment I have, although I do have a small attachment to my sister but at times I feel like killing her. The only other attachment I have is to animals, I love every single one and cannot bare to see them in pain, despite me torturing animals when I was younger. (Which I highly regret, I was a disgusting child.)

I've looked up Sociopath's and they are able to have emotions, however they are prone to outbursts and are rather jittery and anxious, as well as being easily noticed as a freak. I am calm and collected, and no one knows what I really think of them.

So, am I not a Psychopath, or am I some sort of an odd mix? Don't tell me to see a therapist or doctor, because they are a waste of space and if I truly told them my intentions I'd end up in an asylum, which would be rather unfortunate.
