And I'm very sorry if time lines make no sense. after having a talk with my mother about getting him out again she told me she doesn't want her year ruined and she's tiredof hearing about it. 

For names I'll just use letters. (S) is the father of my half sister (hs) and he is a very sketchy. He is an alcoholic who has been arrested many times for it. And is usually under the influence of it.

So it all started about two years ago. Everyday my brother(B) mother(M) and I would be afraid of what this man would do. (S) would drink himself blind and act like he runs the place and would be reminded the only reason he's allowed here is for his daughter. (S) says so many passive aggressive things and would only actually speak to us when he's absolutely drunk. Other than being drunk this man wouldn't look our way. That is unless he absolutely needed something from one of us. 

Fast forward sometime about a month or two and he finally gets arrested and is taken away for a year for a dui he was awaiting trial for that whole year. It finally seemed like (S) is gone we don't need to worry about him anymore. Once when we heard he was out we all said don't let him back in. We all know he has no where else to go. So with that in mind I locked all the downstairs windows and the doors. With this peace of mind I go off to work and come back after the shift to see a ladder to the second story and see his car there. The man broke into our house and I said he has to leave. (S) tells me "I'm just going to live here, you can't get rid of me. This is how it has to be" so with that I threaten to call the cops and tell my mother about it. He eventually leaves, but like he said he came back. 

But before the year ends one more thing comes from this. This incident here is why I will never look at this man again. (S) doing what he does best and is drunk raging about how things are awful here and how things are going his way. So we tell Him yet again he has no power here since he only has to watch one child when my mother's at work. He walks off and we ask him why hes acting so mad. At this point my brother walks outside to see what's happening and (S) charges at my brother. Thankfully my mother caught him in his tracks and said he needs to leave and he fought all of it. 

Now we get into this year and his drinking habits pick up again. But they get worse. Instead of one bottle it's two. Now (S) is on a blind rampage. He starts making fun of everyone for months, talking shit about us to everyone who wasnt us. He isolated himself from us (when I say us I mean mother, brother, and me).  We didn't find this out until what really set everything off. We had a family friend come over one holiday and we told him (S) isn't fun to be around, but with that knowledge he said it's fine. (S) gets power drunk like we all assumed he would. And later that night he said all sorts of nasty shit to our family friend. At about 9:30pm (roughly) I hear him yelling viscious words to this man. Things about how he's a shit father a horrible man to be around and waste of alcoholic space. So I run out there and I see him fuming. I ask him to calm down and what's wrong. He tells me and my family that (S) hates us all and how he hates my brother the most. (He says nasty shit I won't go into unless asked.) and we all just say it's the holiday let it be. We go to sleep and I wake up with no (S) in sight. From what I was told (S) pissed all over our couch and left. 

(S) is back and hasn't done anything wrong but he's drinking again and I want to stop it at its core. So with that reddit.. Am I the asshole for trying to get him out of the house. 
I'm aware I shouldn't ask for help but what can I do?

TL;DR My half sisters father is aggressive when drunk and terrorizes my family and I want him out 

Thanks for the time reddit
