wishing his death does not make you bad. It makes you human. You do not say you are going to take matters in your hands to cause his death, just that your mind would be more peaceful if he was dead. That is just pure honesty, and I feel a lot of times the same about the people who have abused me.
I know of what things this man has done to you, to another person I know, and to other innocent victims. It is not things that can be easily overlooked and put to peace in your mind. There is such thing as evil. It is not just a figment of imagination that got it's own dictionary definition. It exists in people, and in some of their actions. I can easily see how the death of one such person could trigger such thoughts to you of another that you, unfortunately, had much more personal experience with.
However you feel, is ok. Do not allow anyone to tell you it is not. That is not fair, it is not supportive, and it is not what this site is supposed to be about.
