Just one member can tilt the family dynamic into dysfunction, or worse, estrangement. Often, it is the parent who behaves destructively. The parent may have underlying personality traits that result in harmful family dynamics. The destructive parent may try to manipulate others; demand support but offer no support; remain inconsistent with rules and operate unfairly. They can also be judgmental, critical, and unaccountable. All of which harms the family unit, maybe for life or even generations.
