Review of Saga of Tanya the Evil

You know I don't get the evil part at all. OK. She is not a friendly or warm_heart fellow but still, evil? She always try to find logical solutions and most of the time try to find a more peaceful solution. we see she even propose surrender to her enemy several times. she even trained her forces with best way. damn i can say she even care for her subordinates. Yes, for sure she don't believe in god and she is not one of those guys who sacrifice herself for other people. but still, why she is evil?
