Am I the only one who thinks hurting someone's feelings is wrong?

I constantly think about this everyday. I don’t know why it bothers me so much.

But when someone picks on me or makes fun of me, it obviously affects me, and that person continues to bother me. My friends say to just ignore them, obviously, and I try to but it’s hard, considering it happens a lot. Everyday it’s something different with the name calling.

But what really confuses me, is why do people find joy in making other people feel like crap? Am I the only one who doesn’t feel the need to make fun of someone? And when I do, to acknowledge that what I’m saying is hurting them, and I should stop?

I honestly don’t see how making someone feel bad would make that person want to bother the victim even more. I don’t like this rule. Can we change it?
