Love the way you frame that.
I feel silly spelling it out for you:
Hosting a party is not "antisocial" vis-à-vis your, shall we say, 'like-minded' guests.
Hosting a party in a manner that "frightens"/ "disturbs"/ violates the civil and property rights of your neighbors to the point where they have to call the police is, without doubt, "antisocial."
PS A lack of respect for the rights of others (and "boundaries") is a characteristic of sociopathy.
This episode, though indicative, is quite harmless, if you comapre that to her behaviour after MK`s murder. Regardless of what you think of her innocence or guilt, making fun of the victim ("she f****** bled to death", "sh** happens) and laughing besides MK`s mourning friends, turning cartwheels in the police station and thinking about writing a song about the murder leads you inevitably to the conclusion, that this person either:
-hated the victim to her bones
or
-showed ample evidence of a sociopathic behaviour
or
-was about to lose it, because she committed a non-premeditated murder
or
-any combination of these three things
As committing such a brutal crime, be it premeditated or not, is obviously sufficient ("thank you" Kevin Lowe for your "lesson" on necessity and sufficiency) for being a sociopath, it comes down to, she
-hated the victim to her bones
and/or
-she she showed ample evidence of being a sociopath
Personally I tend to rule out possibility 1 as everything I`ver read so far gave me the impression, that their relationship was in fact not that good but definetly not driven by hatred, too.
But, why the hell am I exerting myself to write this, I`m sure, there wil be a superficial four liner response post:
"AK didn`t hate MK, there were photos from both of them on AK`s laptop. Moreover AK ended an sms to MK with an "X", which means giving someone a kiss. So, in fact they were good friends.
And AK is a totally normal college girl. Everyone reacts different to traumatic events; her behaviour was nothing out of the normal."
