Which is more powerful in your opinion? I mean like which is a more greater force and which is more effective on people. They both can change a person's whole mind state and completely turn their views around. People that are loving seem to have the upper hand in life, because they care more. People that hate more than love are usually people sick of the world and everybody in it.
Now. What is a more powerful force? If someone killed your loved one, what would you do? You would probably use the full strength of hate in your power just to kill that person. Now people that hate, care less than someone that loves. I mean in the real world, you have people pissed off at their lives destroying other peoples lives, because of hate. Even though, they are very equal. Hate is more powerful than love in my opinion.
