You can easily see how much violence is present all around the world for trivial reasons, You can see how much kids are bullying others just to show their superiority. Cruelty is part of human nature, and people tend to affirm themselves by showing violence.
That cruelty is a part of human nature is undeniable. It's that, deep down, we do individually and collectively want to instead give and receive kind acts that I argue for; it is possible to raise the kindness to a level where it's far more prevalent than actions resulting from our cruel side. The example of a bully, who acts this way against another due to feeling inferior whether it's because of neglect at home or any other reason, shows this perfectly because the same person who bullies perhaps wouldn't be bullying had this aspect of their life been different, that is if they'd received enough attention and respect to feel valued. Somewhere along the line we as humans have made decisions which promote violence but learning from mistakes is a human right and we've seen countless occasions where the most heartless bullies have changed, apologized, and refused to take part in such a thing ever again. Even if this is after something so severe as a bullying victim committing suicide. It's then when they'll never go back. Like when hate-group members find their humanity by connecting with a minority group member who they'd previously have wanted dead. Even now when there's so much media focus on harm done or threats to one another, and so much temptation to put others down so as to have more material things or be seen as superior in other ways, there are acts of kindness happening all of the time. Sometimes at the risk of losing everything which our culture points to as being of importance.
