What you've stated all make sense,
and yes, it bugs me when people try to contemplate if they have ASPD or not because a few key characteristics were conspicuous when they were self-scrutinizing themselves like twats.. I've seen it on the Psychology & Mental Health sections of Yahoo! Answers numerous times, there were so many questions flaring up relating to it that you wouldn't be able to exert your knowledge to educate all of them. Even if they had it, they wouldn't give a flying ***** so why are they asking people for some form of approval?
I can't say that I have not been altruistic before, I've helped multiple people multiple times because they happened to be at that place at that time where I was present.
An old lady at the supermarket asked me to carry her trolley and her groceries to her car in the same parking lot my car was in since she thought it'd too much for her, I did it, mainly because I could and I was going there anyway to leave.
I've witnessed a fight between 2 adolescents near the playground that was right off the beach then another dumba$$ decided to be the bigger dumba$$ and jump in so it was 2 against 1.. I calmly broke it up by segregating and yelling "Get off the kid you talentless twats!" and told the kid who jumped in that he was an idiot and they walked off, all in different directions of course

. Again, I did it because I could, I wouldn't of cared if the kid who was ganged up on would've been injured, but as you can see, I prevented injuries from occurring.
