We are ( as cliche as it may sound)unique and as such there will never be a universal thought. Most seek some sort of dominance. Arguments for example are proof of that. One seeks to be right. We seek power and the ability to use it in such a way as to gain more until there is no other. Now there are always exceptions to this, but most on some level, want to be above another in some way and that causes allot of struggle. I would say most want to live a peaceful life , but with differences comes conflict of interest. Also, genetics put the fight into us. We are bred to survive and overcome all that we see as an obstacle which at times includes, each other. All animals fight one another and at times kill each other.
