I'm not making myself a victim, I just came to ask for help. Whoever wants help, whoever doesn't, just ignore it.
If someone who has tested it like I did and didn't like the result, that's what happened. Just type the command in the terminal:
sudo pacman -R gnome-desktop
If you have a package that is preventing you from uninstalling, you will need to delete it. BEWARE, only delete what you are sure will not compromise your operating system.
I only needed to delete what had "gnome" in the package. I restarted and the system worked 100% normal here.

Note: here is the solution for my "messy" system.
