Why Are People Cruel?

Why are people cruel? Do they get off making, watching, causing, pain in those that walk across their path?

Why do people belittle others? Do they believe that they stand on a pedestal and it is their job and/or right to criticize those who walk below?

Why is that on the one good day, the one day I can actually walk on solid ground… someone comes along to ruin it all… The one day I actually wake up with a smile on my face, not the one that is faked and forced, but the one that comes naturally…

Why as human beings do we hurt each other… why are we cruel
