Terror used to control those who are weaker than you such as: hitting, threatening, whipping, burning, is a form of abuse. A rational person with a decent education and proper upbringing usually would know better than to abuse their child by using terror tactics as if they were prisoners of war.
Children who experience this type of abuse need years of counseling because they grow up damaged. Everyone needs a safe place to grow. Look at the concentration camps and the children living in similar situations with daily terror. Children believe that there is something wrong with them.
Yes you were abused. Your parents needed help to control their temper. Abuse to others weaker and smaller show brut ignorance [lack of education], lack of the capacity to love and no parenting skill understanding. Parenting skills education ought to be required!
