would someone please explain people to me

why do we feel we have the right to pry in other peoples life?
why are we willing to hand out hurt and pain instead of care and love?
why are we so quick to judge?
why do we not realize that our action have consequence's?
why are we will to believe the worst juicy rumors, and willingly help to spread them without realizing that we are hurting someone that has feelings just like us?
what will it take for us to be more understanding and mindful of each other?
