is it wrong that I hate my sister who made my childhood hell

I (17) live with my parents and last year my sister (27) moved home. Because of the age gap between us we weren’t THAT close when i was growing up and when I was an age that I could clearly remember things she was 18 and had moved out.
Growing up, her and my parents never had a good relationship. My whole childhood I just remember her shouting at them and hitting my mum. I remember police coming to my home and talking to her, parents calling her school. And my mum told me about how when she was holding me when I was a baby my sister would hit her and pushed her onto a road once. She’d throw stuff at my dad and oh my god I cannot stress how much she’d shout. I learnt a lot of the words she used to call my parents when I was 3.
I can’t describe how much she’d argue with my mum and dad. When she’d argue with them she’d always take me to her room and just talk to me, like I was an emotional support thing (I was 3 I couldn’t understand what she was saying). I remember once she was shouting in the car with all my family in it and my dad ended up crashing into a roundabout. Essentially she hated them.
Idk how to word this without sounding crazy but since the age of 9/10 when I try and study/focus on something and it is silent I sometimes hear shouting and arguing in head. I swear I’m not crazy. But seriously, why is that? I told my brother (23) about this a few years ago and he said that she affected him a lot when he was growing up with her. (memory unlocked: once she tried going after him with a hot iron)
Anyway she was done with school, she moved to Germany for a year and then moved away to live in London. I don’t think she ever knew what to do, she changed between a lot of things; she started 3 different apprenticeships she never finished. She rarely visited us at home and showed little interest in my family, she was distant.
I think she’s a very random and spontaneous person. She had a job at a butcher’s shop 2 years ago, and while there, she had an injury and part of her thumb clot cut off. Since that day, everything changed. She decided to become closer to my parents. She moved back home and 6 months ago started her 4th apprenticeship. Everyone was happy and convinced she had changed for the better. But I just cannot forget the person I saw growing up.
She tries so hard to make my mum like her. But I can’t forget the vile way she used to talk to my mum. Whenever my mum can’t hear, it’s like a switch flips in my sister, her voice completely changes to such a sour tone and she speaks so horribly to me.
It’s so draining.
And whenever I talk to my mum about it she just says ‘okay, yeah, yeah, right’ she doesn’t validate how I feel AT ALL. I feel so replaced by my sister, everyone treats her like she’s a kid. I won’t lie, I’m jealous, I want more attention from my mum. But it’s all being redirected to my sister. I feel like she’s taking my final year of childhood away from me. And it’s even worse since she took all the attention from me when I was younger from all the arguing
And omg, my dog. She provokes my dog all the time and does things he doesn’t like all the time which result in him growling at her. When I kindly advise she shouldn’t do something she gets so angry and starts shouting at me about how I control everything she does. But my interests only lie with what is best for my dog.
She’s know been living at home for the past year and makes me feel like **** daily. I’m so done with her. I pray one day she just moves out. She’s so emotionally immature. She earns more than enough to have her own place.
Sorry this is so long but I’m just so sick of her.
