My dad is a complete asshole, what can i do to make it stop??

My dad is a complete asshole, what can i do to help him? i know most of you will say, "oh hes still your father, show him love", i posted a couple examples of what a "father" he is.

1-He gets aggrovated over little things, like he got drunk and smashed to tv remote because the batteries were dead, and when he was sober, he called me and said" why the **** did you break this remote" , im not a dick, i show respect even when faced with a ********,so, i said, it wasnt me, dad", and he threw it at me, and he just started pounding the tv cause he didnt have a remote.

2-He never lets me leave the house, i rlly dont want to brag or show off, but im strong, like stronger than him, im always out of the house when he is cause thats my only chance, my friends called me, and he said, "tell your ***** friends their worthless, and you can leave", from this day, i only have like 2 people i hang out with, my cousin and my best friends, hes from europe, he understands asshole parents from his country.

3-He always threatens me with stuff, last year i worked my *** off at a comvience store just to make $500 dollars, he has a nasty dent in his car, and i fixed it, i spent all my money, and i told him im sorry(even tho i didnt dent his car, nor did i have to apologize for anything), but he just said"...i didnt ask you for it", i thaught this would smooth our relationship out a bit but nothing. He just returned to being pissed.

4-Other than the $500 i had saved up, i had $3500 saved up, since i was 5, saving up every penny, even being stupid and cutting school to work, i went and bought myself a dirt bike, a yz85 if you care, straight from the dealer, which was 12 miles away, and i didnt have a father who cared enough to give me a ride, i would have paid for gas, and his troubles, but i thaught, whatever at least i dont have to see him, so i bought the bike home, and my mom just went "WOW, it looks beautiful, i remember my first bike", i said thanks and hugged her for agreeing to let me buy it, but then my dad pulled in the drive way, came out and just stood there, and noded, my mom, now gave me a serious look, go, put it away, it wasnt an angry voice she just wanted me to put it so my dad ddint get mad, the next day i came back from school, and i was SHOCKED, both wheels were deflated and the engine was in peices and there were hammer marks all over it, my dad has no respect for my things, he doesnt know how to treat a woman, or a child, or EVEN another man. Im still in shock now, and i grew 3 years older, im 16 now.

My dad is an alcholic, but worst he has a gambling problem, he getts stress everyday when he stupidly walks into the casino with his $1000 check and leaves with $1, he is the worst person ever, i dispize him in every way, one day when i was 14 my girlfriends came over, we werent doing anything, just a bit of studying,, my dad came in and just looked at her and went "you get the **** out of my house,before we have problems", what can i do to calm him down, its not just stress, hes just naturally a *****, all my granddad every did was hit him, so now hes passing it on to me, i cant talkk to police because i dont want to stress my mom any more than she is now, who can i talk to???, i dont want it to end in violent, but if i have to , i will!
