The truth has been found by Jackel 999, FyroKnight and Furrin Gok.

We are all important for the progress of this world, don't let anyone tell you that you can't do anything.

Pain brings suffering, that suffering however is transformed into more agony and eventually it explodes. hurting someone else over time will just create a bomb ready to blow, and the explosion will affect the culprit.

Not all people that seem cruel truly are however, we must remember that there is a reason for someone's anger, however blind wrath and damaging someone else for the mere sake of revenge will eventually come back annd hit you were you least expect it.
