I think that I might have antisocial personality disorder, what do you think?

Recently one of my colleagues committed suicide and noticed that my other colleagues felt quite bad even though they didn't know him as long and well as I did. Despite that it didn't really affect me that much or even at all I just did what I always did. I put on my sad face and acted as everyone else. So I thought back and realized that I'm different than others. I've read about antisocial disorders and I found out that even in my childhood I did things that are connected with it. Things like constant fight with my classmates, harming and killing small animals, stealing, lies and such. I often manipulate people around me to think that I'm a good and hard working person and I don't feel bad about it at all. It just makes me proud of myself.
I decided to complete some test that has been created by competent people and I've passed!
