Someone help

I know that one of the things they do is like animal cruelty and that really disturbs me. I fear I might have done something when I was a child and I just don't remember it. A memory popped up right now. I remeber once when I was really really young a snake appeared in my street. Everybody around went to see it, I think it was kinda small I don't remember that well, the only thing I remember is that I think I was riding my bike and a man killed the snake and to make sure it was dead I I rode the bike over it. Does that make me a psychopath??? I never hurted any animal and I never wanted to. When I was young I even wanted to be a veterinary. But does this makes me be a psychopath??!??!

im always worried about something when im bored and for a long time i have been scared of being a psyhopath how do i tell myself im not someone help and tell my how do i tell myself im not is this ocd?

So it started i think a month ago when i saw a video about a psyhopath and it said that they start by killing animals when they are young and when i was younger i was killing grasshoppers and from that day i had a fear in my head what if im a psyhopath and don’t know it. i couldn’t get the fear out of my head its like alaways on my mind and i got so scared that something is wrong with me so i started googling stuff because i was so scared that i have a mental illnes so i started reading about stuff one google and i saw a illnes called Schizophrenia and i read about it and when i saw the symptoms i got scared that i have them because i have felt kinda stuck in my mind because of the fear and now im scared that im in the early stage of schizophrenia. Please i just want the fears to stop someone give me advice i just want to live a happy life and focus on my school but its hard because of my fears please how do i know that i dont have schizophrenia because i have read about it i feel like i actually have the symptoms im so tired i would love some i advice please
