A man, sometimes with the best of intentions, who falls in love with and marries a woman with children. Someone that everyone gangs up on and that will never belong even if he treats everyone very well. Step-fathers-mothers-brothers-sisters aren't necessarily "wicked" because of their behavior, but are because of the nature of the situation. Some stepfathers are messed up, but some aren't and are mistreated by the majority of the household. Years of hurt sometimes surface as anger and everything falls apart. Unfortunately, divorce is necessary in some cases.
Stepfathers aren't all bad.
