One: The Marine Explanation. According to Marine, antis are born out of a feeling of love, twisted into hate. So imagine fans of a girl, someone who believes themselves to have been important in the girl getting success in the first place. Now imagine that girl does something that the fan doesn't like. That fan will go ballistic sometimes, and feel that the girl he loves betrayed him. He wants a sense of control back, and that sense of love turns to a sense of hate, or worse, a sense of twisted love, thinking that they need to control the girl as a show of their love.
Two: The Path of Envy. A girl who succeeds in spite of circumstances will draw the ire of those who cannot succeed. Think of it this way: imagine yourself as a bird with a broken wing. You live in a colony of birds with broken wings. None of you can fly, and that sucks, but you all at least share that burden. Then one day, one of the birds starts to be able to fly again. They soar and can see the sky again. You don't know why they were able to fly, but you weren't. For most, that's it; they accept the fate and wish them luck. But some people, they feel scorn, resentment, envy. "Why didn't I get that gift? What the hell did you do to deserve this that I didn't do? This isn't fair! Why should you be allowed to fly while I'm forced to bear this burden? You should be stuck down here with me! Every second you spend flying is another second you insult me by robbing me of that gift!" That's the logic of Envy.
Third, and the one I consider "without emotion," is the Path of Boredom. That's teenagers, NEETs, people with nothing in their lives, who just tear things down because they just get pleasure from breaking stuff. The Sid Toy Story of the world, the kid who kicks down sandcastles in the sand. Those people are the ones who have no desire, who just exist to get attention.
Those are the biggest reasons, I think.
