My brother was wanted on a warrant for refusing to stay in rehab. (Hard drug abuse) 
My father's father wasn't doing so hot so a bunch of my family decided to head down to Texas to visit. I stayed home and took care of my dogs and other things my brother spent a few nights here aswell.

I came home from work not long after it find my brother and a female who where rather naked fuckin' on my couch.

Now I get it hes been in rehab and blah blah but this just set a fire under my ass because I dont trust strangers very well, and I have a fuck ton of stuff worth a good bit that is easy to steal. (Drug addicts dont care who they still from even my brother sold a collectable of mine worth nearly $900 for a bag of weed).
Moving on we got into an argument and I told him that he can stay the night but he'd have to go back to his baby mother's house. 

Later that night I get a call from my dad saying to check on him becuse he aparently took a bunch of pills and was trying to kill him self (spoiler alert: he didnt)

He then faked to be dead at the keybord until I tried to check his pulse (ice cold hands) and then followed the trick with slurred words and all that. So to actualy test him I called an ambulance and he was instantly sober and took off and ran into an officer down the block. He was arrested. Now my family is telling me I was to hard on him. Aparently they wanted him out for his daughter photo shoot. (His kid was in Texas to meet her great grandfather)

Am I the asshole? Should I have not done anything?
