Is watching videos of people dying or videos of of gore, haram, makruh or mubah? I cannot find any rulings online

By default it’s permissible. However, if:

1- Watching such videos makes a person aggressive and leads him to have a bad character
2- Or seeing the person dying in that way is disrespectful and it is like de-sanctifying the person (if he is a believer)
Then it would not be permissible
