Is this child somewhat normal or healthy?

The parents sound “too nice”.

I see a lot of parallels with my own childhood.

I had difficulties fitting in and rebelled... until I met some other adult mentors who showed me how to channel my energies and feelings into positive and productive things (not to mention that my dad started to take me to work every day after the cops brought me home for what would be considered "grand theft" today).

About age 13 I realized that most of my friends were being sent to "reform school" and that I better change my ways if I didn't want to spend much of my life in prison. The change was radical... and it took a couple of years before people really believed I had changed in key ways.

Sounds like the parents don't discipline they're child, but it's possible that the child might not be mentally healthy as well. No one here has the medical qualifications to judge the child, especially without observing said child. The parents probably need to have the child evaluated by a mental health professional. If you have a child, or a pet it would probably be best if you didn't leave them alone, and unattended with this child. This child needs more supervision at best.

Keep an eye on it. Dont dismiss your gut feeling and just say its ok. If the kid is off it needs to be attempted to be corrected as young as possible.

Eh, the kid will grow out of it.

He needs a good beating

The first few don't sound bad they sound like accidents? It just sounds like a kid being a kid. When I was maybe about 3 or 4 my parents told me I purposely knocked down kid's forts in my preschool and the teacher kept telling them about it but fast forward and I'm afraid to swat a fly or even tell someone I don't like their cooking lol. I'm told I'm too nice so kids do grow out of it once they grow up and mature a bit more.

Sounds like a psychopath in the making

It sounds more likely that something is wrong, but kids can change a lot from childhood to adulthood, or even childhood to teens. I remember once as a kid, I hit my sister for literally no reason at all, there just was no barrier to stop it, would never do something similar today. As still a kid but older, I used to chop earthworms into pieces just to see how long they would live, again that's something I would never to anything similar to today and later I have actually cried over cases of animal abuse and donated to charity many times. Its no guarantee they will be a psycho when they grow older, but you should be watching out.

Because the "kid" is you.

i think he is possessed
