Not feeling remorse or guilt.

Hello reddit.
ill make this quick, i basicly dont feel remorse, i've done alot of bad things in my life and feel no regret, like i can steal (and have done it) and feel no regret.
I once saw a bunch of insects and killed them for no reason, i would kill a animal if i didn't know it was stronger than me/could harm me, and i would feel nothing about it, just 2 months ago i found a lezard and i took it and cooked it and though it was funny.
Another exemple: Just last week my friend has annoyed me and at a point he pushed me, so i hit him hard in the leg and he started screaming and crying, i laughed.
I also enjoy breaking rules, even the most basics ones once i started making coffee at school just for the sake of it.
I dont even feel empathy toward myself, for a time i used to hit myself when am angry and i still to today dont regret it.
I dont feel regret at all, i get angry if i get caught and rethink how i could have avoided it.
And this is just 1% of the things i've done.
Before anyone says it, no am not intrested in therapy, am just looking for reddit's opinion i have nothing better to do right now.
Also, as long as i remember i dont have childhood trauma or remember being bullied.
Also, i dont manipulate people (i dont manipulate them consciously? but i dont think i manipulate at all) i enjoy talking alot to alot of people but am truly honest only to some.
Also: Funfact about me, I like reading frederick nietsch :D
Thanks for reading i guess?
