Aunt And Uncle Are Abusive Parents. What Can I Do?

Location: Michigan, US.

As far as I can remember, my aunt and uncle have been abusive parents to their son and daughter. Both children are at/under the age of 10. List of offenses include:

- Their biggest offense: my aunt's several murder attempts against me, as well as repeated physical abuse. I have sustained diagnosed C-PTSD and a few visible marks, but since it's been quite some time, they're not particularly recognizable and this probably wouldn't hold up in court.
- Excusing their son's violent behavior towards his sister, telling their daughter that 'that's how boys show they love someone'
- My aunt can be incredibly unsanitary. I recall the kids eating food in the bathroom, vomit not being cleaned up, rotting food on the floor and in their car, etc.
- My uncle was on a really weird carnivore-esque diet for a while. For a long period of time, he would only eat dinner, skipping breakfast and lunch entirely and wouldn't allow himself coffee or water within this time period either. In casual conversation, his daughter told me that he would take his anger out on them, yelling and screaming at them both and hitting his son for no reason other than his own hunger and insecurity.
- Aunt is incredibly strict with daughter's lifestyle, pushing her down a 'wifely path.' She also forced toxic eating standards on her daughter from the age of 6, not allowing her to eat certain meals that her brother is able to eat.
- My aunt finds sexual abuse of women funny. She's ordered her son to inappropriately grope his sister and other female cousins
- My aunt has a lot of anger issues and is very randomly explosive, often escalating to the point of violence.
- My aunt has a tendency to be vulgar around her children, her language getting sexually graphic
- Both parents have alcohol abuse problems, and my uncle suffers from a nicotene addiction I've only seen get worse progressively.
- Daughter in tears telling me she had a crush on a girl in her class once, terrified of what her mother would think. I had to tell her that no matter what she did she could never ever tell my aunt (queerness was what I was abused for. This would otherwise be irrelavent but this gives me reason to believe the daughter could be facing the same treatment I was)
- My uncle was often very physically abusive towards the kids, especially his son. In one instance, I recall that during a sleepover, we were all staying up like five minutes past bedtime talking. He got angry and stormed into the room, picked up his son by his collar, backed up three or four feet, and threw him against the wall, causing the poor baby to land on a wooden crate.

I should clarify that I am safe now. I am no longer in contact with them, nor is the rest of my immediate family. Even still, I want to make sure my cousins are safe.

Would this be worth going to CPS about, if proven guilty would there be actual consequences pinned on my aunt and uncle, and if I do go to CPS, would my report be able to be traced back to me based on the evidence I give? I have no idea how CPS investigations usually go down, and if it were to get blamed on me, even through word of mouth, I fear the worst.
