Holocaust class makes me want to kill someone

You need to seek the aid of a psychologist or possibly the aid of a psychiatrist as soon as possible. This is something you need to take care of immediately.

Dealing with anger takes time and it is easy to learn to control anger, but when emotions such as yours come into play it is always wise to seek professional help.

Good luck and best wishes. 

I am really glad to hear that but in this day and age you never know anymore.. Like you, I feel that same rage and disbelief that someone could do that to another human being.

To think that we are supposed to be the more evolved species of this planet.

Good luck and best wishes to you!
