Should I get tested for mental/personality dissorder?

[Vampiric Pisces]

Ok, let me explain quite a bit about myself.

- I have committed arson on a higher than medium level.
- I killed a mouse. I killed it because my cat had ripped its stomach open, and I thought it should die. I got a tub and drowned it. I liked it. I would probably do it again if given the opportunity.
- I have stolen from houses
- I choke my brothers until they almost faint.
- I enjoy watching real footage of violence and murder (my eyes diolate when watching those things)
- I don't hate people, but I don't like anyone.
- From a young age I had behavioral problems (now I am very calm and collective)
- I wet the bed up until my teens (around fifteen I believe)
- I went through a lot of drama as a child with abusive, psychotic drug dealer step father, pedophile uncle awsell.
- A lot of people in my family have mental disorders and personality disorders.
- I watch a lot of pornography

And that's all I will list so we can move on.

I have been called a sociopath, anti-social, narcissistic, psychopath, etc, etc.
I do not believe myself to be any of these things. Personally, I just don't think I match up with the traits they have. Maybe anti-social, but the rest sound too 'far out there'.
These people have labeled me this from online. In my real life I do not act the way or speak my opinion due to knowing a lot of people will get emotional over them, and I don't want to be viewed in a negative manner.

I have been told that I should see some 'professional help', and so thought I would get opinions myself.

Should I get checked? Would these things go on some sort of record that would not be so good to have when searching for a job later in life?

Thank you.
