I have to hurt others

One of the moments I feel "Life is hard" is,

when I have to hurt others

---

Even if this is someone who I don't want to hurt the most,

I still have to hurt him/her,

in order to.......

in order to pursue what I believe right
in order to be true to myself
in order to be myself,

with a slight hope that
someday, he/she will understand why I hurt back then

No matter how egoistic all of this would sound,
I still have to hurt
