Why is a parent praised for disowning a child that wrongs them but criticized if they forgive?

Here are two father who were betrayed (the levels varied) by their daughters. While one disowned her, the other forgave and still visits her.

Disowned daughter; bond broken

What she did? She hid her mother's affair for nearly a year, deleted the lover's text messages and try passing his baby brother (affair baby) as the father's child. The father was a tech savy and figured out everything. He divorces and disowns daughter. The daughter has been trying to make amends for years but he refuses to ever acknowledge her saying he doesn't have a daughter. He denies her existence since she was 16; she's now in her mid 20's.

Forgiven daughter; unconditional love

She did a whole lot worse than the first story. Her parents banned her from dating her boyfriend. In retaliation, she orchestrated the murder of her parents and two youngers brothers. She was the same age as the first case; 16 years old when she did all that. Only the father survived but he still forgave her. He's a devoted, religious man that believes in unconditional love towards a child till the very end. Somewhere I read that even if she was the mastermind well it's still his daughter.

Obviously both fathers were betrayed (one worse than the other) but if why do people on youtube, reddit and other places called the first father a hero, a man with character and criticize guy 2 for taking the forgiveness route? Why is the retribution route praised more than forgiveness?

Meanwhile the poor dude that lost his family to murder (the daughter wanted him dead too but he survived) was criticized by people for still being in contact with his daughter? He already suffered enough and the people want him to take the retribution route but he believes in forgiveness.
