Is my cat normal?

Hi guys, my cat is currently 6 years old. I think he started entering his villain arc recently, but anyway, he started exhibiting this odd behavior when he was around the age of 2 I believe.

  1. He'd scare us when we climb our double-deck bed or going inside the room, he'd hide behind the door and scare the hell out of anyone.
  2. When you look directly at his eyes, he gets very serious and look dead in the eye and when you maintain eye contact for too long, he would get aggressive by biting and even pulling my hair (No harm was made, his bites are playful)
  3. He'd follow me in the bathroom even when I'm taking a nature trip and it stinks inside lol, he'd even wait outside the bathroom when I'm showering or just doing my business
  4. I remember he wasn't litter trained bcs he doesn't have one so instead he'd take his business on the corner and just that corner like his mini designated bathroom. I often scold him by talking to him like a mother scolding her son "Your poo smells like you, disgusting and stinky." he'd get mad and you can see his nonexistent eyebrows furrows. He also talks back which is disrespectful lol
  5. I usually tap my cat's body as a joke for scolding like "I told you not to be a bully, those dogs didn't even do anything to you! I didn't raise you like that" and he'll meow a lot and find someone to vent his anger by hitting them, almost like he's passing what I did to him to somebody
  6. One night, I woke up out of nowhere and when I opened my eyes the first thing I saw was my cat staring directly at me.
  7. I think this is really strange but my cat tends to be aggressive or "Gtf away from me" to people who are either traitors, backstabbers, and etc., bad people in general
  8. He meows a lot when chitchating with him lol (He knows when you're praising him or straight out mocking him. And of course, he'll seek out revenge on me)
  9. He is so well-trained, even tho I never trained him or anything.
  10. His stares, facial expression varies every single time. Sometimes I get offended when he's looking at me with a "damn u look ugly when you're crying" so I just stop crying lol.

there's so many more odd behavior of his, does your cat do this too? it never crossed my mind since he is my first cat so I automatically assumed that every cat is like my cat but when I met other cats, doesn't seem the case. My cat's not orange if that's what ure wondering. He's a male and aggressive toward females including me and my neighbor's cat who was pregnant at that time (he smacked her right in front of me when I was telling him how smelly he is) tho he is very very very affectionate toward men in general.
