Hatred of the wicked

 
peace,
I don’t really know what it means to hate or be angry. I don’t hate evil people, yes, yes, not even Hamas, for example. Don’t get me wrong(!) – I don’t have a drop of empathy/pity for them or for the Gazans, it’s obvious that they don’t even deserve to be called human beings… I just feel like I live more in love than in hate. For example, when there is, God forbid, a terrorist attack, I feel incredibly sad for the person who was hurt, because I love them, but I don’t have an ounce of anger toward the terrorists. I don’t know what anger really feels like. Am I missing out on something important by not hating evil people? Should I strive to hate them? Do you think there is some kind of similarity in approach with Christianity here? Is that what’s missing in Christianity?
Thank you very much in advance.
