Should you let your 12 year old daughter read johnny the homicidal maniac?

Well to be honest it is JTHM! But then again it is a comic character and my daughter read it when she was 12 and now she's 13 and a half and she isn't killing people. She does however like to nagg me to get her JTHM stuff. I think it's safe but I don't know your daughter soo... Yeah hope this helped
