We can't even find one friend to say they have seen Adnan excessively angry
First of all that is not true, second of all that tells me all I need to know about your lack of experience (as does your writing, it's hardly legible). Sociopaths do not display outburst of anger, they are cunning, manipulative, affable, and charming
I also listed many characteristics above, if you can't find them because you have no clue what they are, like I said look them up.
But because I am sick of the misinformation being spread, I will indulge others who are reading so they can decide for themselves.
Adnan is glib in all his answers and displays no real emotional depth when discussing not only Hae, but his current situation and feelings about prison. The only time he displays emotion in the podcast is when he becomes passive aggressive and hostile towards Sarah for daring to challenge him, or most notably when he gets angry about Sarah bringing up his stealing from the Mosque because he continually needs to control what others think of him and how they view him (the guys in prison for murder and this is what finally gets to him!?!?). He even says it "shook him to his core" that people thought he was capable of this. It's very telling that the only time he displays ANY emotion concerning this entire traumatic situation is when discussing how people view him.
He has no regard or empathy for Hae's family, taking money from innocent people, conning everyone, or this entire situation and it's obvious. He shows a reckless disregard for social norms displayed by: strangling his girlfriend then allowing this entire charade to go on while taking money from well meaning people. He stole from his Mosque for crying out loud and his friends said he even solicited prostitutes in high school. His friends below list countless traits that scream Sociopath (even though they are saying Psychopath which is not the same thing).
