Chacha Jasari Amani Greed fuels almost all other emotions.
Lust? A want of someone else body especially sexually.
Prostitution? The greed of money made one sell her body for money.
Envy? Wanting what other person have for yourself.
Robbing someone? Taking things from others for yourself.
Murder? A way to take out other person.
Revenge? Acting out on your hate for someone.
Greed is the root of all evil because we humans have a greedy way of life. Early age humans did not survive by sharing, they survived by fighting others and taking their belongings. We try to support ourselves, not the whole race. Even love in a twisted way can be fueled by greed. Thinking someone belongs to you, or should belong to you, is greed. Until only recently in human history do we accept that the Earth revolves around the Sun. Go back a thousand years, and the Sun revolves around the Earth and heaven help the fool who says otherwise.
