Why people are always fighting? Why we can not leave in peace and friendship....?

It's because we're taught to focus on the confrontation, the frustration, and 'defend' our ego, especially the last part is also why people are so bad at relationships these days, they can't connect, form that team/unit needed to have a lasting relationship(often they're even competing with their partner, keeping score in relationships).

We don't necessarily need to fight, the problem is though, it requires a lot of emotional maturity, you need to be aware that you have a choice to engage in a conflict, or you can say 'no, I'm not fighting you'. Everybody has that ability, it's simple assertiveness, you defend your boundaries, and respect the boundaries of others.

Because...since we were little we have been trained for competition. Who had the best whatever in kindergarten and it gets worse every day. Then when kids get older, some kids flaunt their happiness/ success/ whatever : girls flaunt their boyfriends, bodies, making other girls envious. Guys, they well, they think all about girls really so other guys get jealous if they have a girlfriend and they don't. See, we are just trained for competition and you see it everyday.

People can't live without conflict, which is usually why parents complain about heir jobs and children and why people start rumors, to shake things up.

contradictions are there because failure of understand the earth,earth contains peoples with different views,thoughts(pluralist society)but only tolerance and respect among people will yield peace and harmony.conradictions are natural things to people due to our difference in level of thinking,judging(human behaviour are varies).

Because eventually there is that one asshole who doesn't care about empathy and starts knocking down dominoes.

if we want yes.but hwen someone is greedy and not satisfied with his/her own right of sth,then these confrontations happen!

Sa da tay, wa-da-tah!

Because it makes us ALIVE!
