I think about driving over people while I drive
That sounds scary, why do you think of doing that to others?
It's my opinion that they deserve it for crossing my path
Intrusive thoughts may be quite disturbing, and this is definitely something like it. You shouldn't act on such things, it's extremely dangerous and you can get in serious trouble. Do you think you'd want to try talking to a therapist about this?
School shootings also!
