I think one of the most dangerous parts of deep insecurity is failing to realize your ability to hurt others.
You downplay your role in other people’s lives. You think no one could care enough about you or love you enough for you to be able to hurt them.
But people do care about you. You mean something to someone. And part of realizing your worth is realizing that another human being cares about you, and that you and your actions really do have meaning.
