There's a very unsettling book called "look what you made me do" by Megan Norris
It goes through various cases of spouses killing their children to get back at their partners as a type of revenge.
Very spooky. One of the most common scenarios in the book was a husband who finding out that his abused wife had started divorce proceedings/was in the process of leaving the abusive relationship with or without the children and the man taking "action."
I am in no way implying that lloyd will do anything like that but it's interesting none the less
