Is it normal to hate people on and off?

In a nutshell, there are a few people in this world I've come to care for. As friends, as people I can trust.

So those people. I care about them. But even then, I can't help but hate. On and off. For no reason. One day I'll be good with them, the next I'll want to tell them to just go rot somewhere and stop tainting the air with their rotten existence. Emotionally, that's how I feel. It's intense. But logically -- I shouldn't do that. Because it will go away in a day, or a few days. The feeling will pass, but it will also come again. My brain tells me not to shove them away because it's wrong. My feelings are burning holes in me and I can't breath with all this venom in my chest.

I've felt this way since I was little. I know when I was in second grade I would frequently vocalize feelings like this because I didn't know better. I learned quickly that I should bite my tongue because it wasn't right.

But is this normal?
