riddle me this

I am the nightmare you wish would never come into your lives I don't know love, your biggest military's might is nothing compared to my anger, I hate you all for being here, no discrimination, nothing you know can ever stop me, I'm a giver, to all until you treat me wrong,I allow you to hurt me, without a word, because when you hurt me you destroy yourselves, that makes me the happiest of all, If I release my might all will die I don't care about anyone or anything. who am I
