What would have happened if there was no emotion like hate or anger?

John Lennon wouldn't have written the song Imagine, well because that would have been a reality.
No borders meaning we wouldn't be spending so much money on guns and tanks. Leading to No poverty.
Because all this money would be used to feed hungry people and educate the uneducated, actually there wouldn't be need to do that because there wouldn't be any one uneducated or hungry. So all that money would be used to actually make an interstellar travel instead of making a movie on that.
