I want to spit at people walking below me whenever I'm in a balcony or just above ground level
I'm shocked by your statement. What makes you want to spit at people?
Life would be a living hell for them, I will not let them live in my world
It's inappropriate to spit at other people. This behavior is illegal and will have serious consequences. It's best to show others the same respect that you would want shown to you.
I will make them my personal bitch. They better learn their place or they will pay.
It's important to respect others if you want them to have respect for you. Thoughts about controlling others and violating them are negative and will lead to a more negative and unhappy life for yourself.
