why do we gotta hate eachother?

im very sad look at this world of ours were tearing it apart people are dying out of hate right now and nobody is doing anything about it well why not? hmm? i just dont understand we all just need to stop for a second and realize what were doing is rediculous... this life is short already so why do we feel the urge to incorperate greed violence and hate into it ? its so rediculous we will all be dead at some point so why cant we love one another i belive we can i really do there will be a day were people will stop the killing and the hate and we will cooperate together out of love and compassion that day may be very far away generations away maybe but hey anything is possible righ?
