I'm starting to hate my sister and I feel guilty about it

One of the moments that changed how I see my sister happened when we were having a conversation and I simply gave my opinion. Instead of disagreeing with me, she became angry and physically attacked me. I was injured badly enough that I was bleeding to death, and what hurt even more was that she never apologized or showed any remorse afterward.

And she keeps calling my mom bad names all the the time and cussing her, She became calling mom a whore all the time and whenever I get mad she says I'm overreacting, And it really hurts cuz my mom is currently in jail suffering, and she keeps saying things like she have to die from hunger

Ever since that day, something has felt broken between us. I stopped feeling safe around her. Every argument, every insult, every attempt to control me brings that memory back. I keep trying to remember the sister I used to know, but it's getting harder. The guilt comes from the fact that she's my sister, but the truth is that I'm starting to resent her for the fear and pain she's caused me. And the worst thing is that she keeps joking about it like it was funny.
