Can emotional abuse in childhood cause people to become fake or dishonest?

Every liar I have ever met experienced bullying or emotional abuse or physical abuse as a child.

I would say I am more honest than some other people, because God gave me vicious punishments when I was fake or vain or greedy as a child.

My boyfriend hates certain people in my family for their morals and values. But if God did not punish me so frequently when I was a teenager, I would be just as immoral as the people my boyfriend hates.
